Errors, Inconsistencies

LWB1	p. 27	Paragraph "Mustering Out": Jamison receives three extra rolls by virtue of his rank (5), not two.
LWB1	p. 27	Paragraph "Mustering Out" and next paragraph: Jamison cannot receive middle passage, as no such entry exists in the Merchants column of the benefits table. Also affects credit balance in his UPP.
LWB1	p. 41	Paragraph "Armor and Protection": "The weight of personal armor ... is not affected by the weight rule." - except for vacc suits. [CotI, Axe 2017]
LWB1	p. 42	Paragraph "Drawing", last sentence: "... for the purpose of a first shot." - could also be a swing.

LWB2	p. 27	Second paragraph "To prepare a data card": The order of "2) power plant..." and "3) J-drive..." is reversed with respect to the example (p. 30).
LWB2	p. 27	Second paragraph "To prepare a data card": Instructions state to list M-drive and J-drive letters. The example (p. 30) also shows acceleration and jump range.

LWB3	pp. 21-23	The described categorization, specifically as it references character generation rules (p. 21, paragraph "Modern Transportation"), does not align with the changes to Vehicle skill (LWB p. 154).
LWB3	pp. 29, 33	The table referred to as the "special attributes table" on p. 29 (first paragraph) is titled "Animal Attributes" on p. 33.

Unclear or Confusing

LWB1	p. 22	After the errata change to Vehicle skill, are grav belts considered part of the Grav Vehicle category?
LWB1	pp. 30, 33	The listing "Combat Procedure" on p. 30 does not state clearly whether all targets and attacks should be declared before any throws are made. The same applies to the paragraph "Basic Required Throw" on p. 33, second sentence: "He or she must then make a basic throw...". Is the word "then" here meant to imply that the throw is made immediately after the target is declared? This would give an advantage in that attacks could be declared based on knowledge of prior throws despite all attacks conceptually occuring at the same time.
LWB1	p. 33	First paragraph: In what order should the characters (player and non-player) state their movement status?
LWB1	p. 33	Section "Combat Resolution": "A series of throws, in which each participating individual capable of making a combat throw makes one, is called a combat round". Does every individual have to attack if they can? (Presume no.) Suggestion: "... in which each individual capable of doing so is allowed to make a combat throw, ..."
LWB1	p. 34	It is very hard to tell directly from the text who or what determines the particular characteristic that a regular (i.e. not "first blood") wound should be applied to. (Presume defender's choice.)
LWB1	p. 34	The words "wound", "wounds", "hits", and "points" are used without clear definition, making it hard to tell from the text that "the first wound received" refers to (presume) the sum total of damage thrown.
LWB1	p. 34	"As a result, first blood may immediately incapacitate or even kill": The sentence confusingly seems to imply that somehow otherwise the wound could not incapacitate or kill. Suggestion: Replace "immediately" with "easily".
LWB1	p. 34	"Once a characteristic has been reduced to zero, further points...": The text does not make it clear how to determine the next characteristic that "overflow" damage should apply to. (Presume the same way as the first.) Suggestion: "... further points must be applied to other characteristics determined in the same way." Move the sentence to the beginning of the paragraph to bring it closer to the mentions of how to determine the affected characteristic.
LWB1	p. 34	"Round fractions against the character" (presume down): Replace with "Round fractions down"? NB: LWB p. 155 states "round down" (only) in the context of characters who never go unconscious.
LWB1	p. 35	Section "Expertise", paragraph "Parrying": (a long gun) "is treated as a brawling weapon (a cudgel)". However, Cudgels are classified as polearms, not brawling weapons in section "Combat Equipment" on p. 37. Should the parenthesis on p. 35 be changed to "(a club)"? Otherwise it is unclear which skill to use (Brawling or Cudgel). NB, 1977 edition: "... uses the gun as a brawling weapon (as a club, for example)."
LWB1	p. 36	Section "Morale": "+1 if the party is a military unit". Does this mean a unit in active military service? Can a "party of adventurers" (first sentence) be such a military unit? If not, should "of adventurers" be removed from the first sentence?
LWB1	p. 36	Section "Morale": "-2 if the leader is killed". Does this modifier apply only when killed or also when unconscious? While the wording is clear in itself, brevity, surrounding mentions of "casualties (unconscious or dead)", and the following questions confuse it. (a) Do "leader present" bonuses still apply when the leader is unconscious? (Presume no.) (b) Do bonuses of a new leader apply immediately (in the same round)? (Presume yes.) (c) Does killing an unconscious leader who has already been replaced still incur -2 and if so for how long? (Presume no.) Suggestion: "+1 if [any] leader (leader skill) is present [and conscious]; ...; -2 if the [current] leader is killed (...)"
LWB1	p. 42	Paragraph "Drawing", last sentence: "... achieves surprise..." - make clear that this means essentially an extra attack?

LWB2	p. 14	Fourth paragraph about bis models: "treated as the next higher level for jump support, but as the next lower level for software selection". On its own, "next lower level" could be misunderstood to mean one level lower numerically. Suggestion: "but as the [base] level for software..."
LWB2	p. 31	Game Turn Sequence, Native Player Turn: This section is word for word identical to Intruder Player Turn with only the roles reversed. This is not obvious since the text only defers to the table (p. 26 bottom). Suggestion: Add one sentence below "Native Player Turn" and remove phase descriptions (retain letters and phase names): "Same as intruder turn with the roles reversed. A. Native Movement. B. Native Laser Fire. ... E. Native Computer Reprogramming."
LWB2	p. 36	Last paragraph: Point out that the sample planetary template is not at the standard scale as described? Suggestion: "The sample planetary template (of reduced size)..."
LWB2	p. 39	Maneuver/evade: The wording "take the fraction of pilot skill and drop any fractions" is confusing. Take which fraction and drop it along with all others? Suggestion: "take the indicated fraction of pilot skill and round down".
LWB2	p. 39	Auto/evade: It is unclear how exactly A/e is "similar" to M/e and what "at a lower level" means. Is it similar in that it allows maneuvering, i.e. acceleration during the movement phase? (Presume no.) Can it be used without the maneuver program? (Presume yes.) Or does the wording "use of the maneuver drive as required" under M/e mean to imply that evasion requires the M-drive and therefore Maneuver? Suggestion: Switch the order of paragraphs, explaining Auto/evade first and Maneuver/evade as an extension of it. "Auto/evade is a program which automatically produces minor movement for a ship (independent of the maneuver program), thus reducing the chances of the ship being hit by laser fire; it allows a defensive DM against laser fire of -2. Maneuver/evade is a series of six programs that are similar to auto/evade, but perform at a higher level. Each has a DM based on pilot expertise (take the indicated fraction of pilot skill and round down). In addition, these programs allow normal use of the maneuver drive, in lieu of the maneuver program."

LWB3	p. 6	Fourth paragraph: The world characteristics are introduced, but it is not mentioned that these form the UWP.
LWB3	p. 6	Paragraphs 7-8: The subsector index is described without reference to the World Data Format as shown on p. 12.
LWB3	p. 7	The formula for planet atmosphere can yield values outside the defined range (0-12). The text states no rule for dealing with such cases (referee discretion notwithstanding). Clamp or reroll? Same for government (range 0-13), and law (0-9).
LWB3	p. 7	Hydrography results that go above 10 should be treated as 10; results below 0 should be treated as 0. [Rob Eaglestone, 21 Feb 2022]

Status Uncertain

LWB1	p. 11	"The Other career should get two skills per term just like Scouts." [CotI, daryen 2021] Note: "The 'other' career is strange, and double skill would seem to balance it, however I think there might be better ways." [Rob Eaglestone, 21 Feb 2022]
LWB1	p. 14	The cash table includes entries for a roll of 7 for the Navy, Scout, and Merchant careers, even though such a roll is not possible (these careers cannot yield Gambling expertise).
LWB1	p. 15	Service Skills Table, Army career: Should "Air/Raft" be Grav Vehicle? Cf. pp. 17, 22, LWB p. 154.
LWB1	p. 15	There appears to be no way to obtain ATV expertise from the acquired skills tables.
LWB1	p. 15	Both education tables are titled "Advanced Education Table". Consider text on p. 10 (second to last paragraph): "The fourth is available only through advanced education". Should only the fourth table be called "Advanced"?
LWB1	p. 17	Should "Air/Raft" skill be Grav Vehicle? Cf. p. 22, LWB p. 154.
LWB1	p. 18	Should ATVs (and AFVs) be covered by wheeled or tracked vehicle skill? Cf. p. 22, LWB p. 154.

Dismissed

LWB3

pp. 7, 12

Should the formula for hydrographic percentage have stayed 2D-7+size, matching text and/or checklist in other books (LBB3, TTB, LBB6) and software (GDW Sector Gen, Challenge Magazine 26)? Has the errata (LWB p. 160) been applied incorrectly? [CotI, chalimacos 2021] No. "T5 has the resolution of [this discussion], so should be applied to correct the error. [The] formula is 2D-7+atmosphere with the usual mods." [Rob Eaglestone, 21 Feb 2022]
