I thought it would be a good idea to collect the errors/unclear parts of the rule book, so we have a collected page, which could be used as a first errata source.
(I try to collect all things from the thread into this first post, ordered by the numbers. Things where it is not certain that they were intended as written, or if its just not clean written are marked as [uncertain])
2.6, 2.8: Does a canceld action card count to the "multiple action cards... cannot be played" limit?
19.3: What happens if the reinforcements are empty, and one has to be placed from the reinforcements? Taking from one of the pools is just ruled for the Diplomacy Strategy Card in 30.2
20.2: Commodity is supposed to be limited by the number on the faction sheet, not the number of commodity tokens (factor 3 difference, as there are tokens with a value of 3)
52.13 [uncertain]: 5 Stage I, 5 Stage II objectives: same numbers for a 14-point game? (similar: is three the limit for the secret objectives in a 14-point game?)
59.1: In the 3rd paragraph "... towards the space dock's production limit..." should read "... towards the producing units production limit...".
60.3 [uncertain]: According to rules, a player can trade his own card back. When a card is "returned" this way, 60.3 should not "trigger" (the wording should be "If a promissory note is returned to a player due to resolving it,...")
65.3 [uncertain]: Does a ship have an attribute, when its not "0", but "-". Point: Fighters have "-" Move, and flank speed increases this by one, but assuption is: "-" fighter dont get "1" movement. (Assumption: the only reason that the move is printed on it, is to indicate, that it can be improved with upgrades).
67.5: Bad/Wrong Example for paragraph 6: Destroyer roll vs. Dreadnought roll. According to paragraph 4, the roll of the unit with the lower combat value happen before the one with the higher. Afaik (I dont know the actual techs & action cards) there is no scenario possible that a destroyer has a lower roll than a dreadnought. So, in the beginning there is now way the player rolled for his destroyer first.
87.4, 87.7: If playing 14-points game, replace all instances of 10 VP with 14 VP
88.3: Rules have different wording than the Strategy Card "Warfare" itself. (My assumption) The rules are correct, the SC must be corrected (i.e. not only production with one space dock, but with one unit).
"Hyper Metabolism" tech card: "2 instead of 1" makes no sense, as you gain usually 2 CC. Intended: "3 instead of 2".
"Skilled Retreat" Action card: "Then, place a command token from your reinforcements in that system" leads to 2 questions:
Is it allowed to retreat into system when there is already an activation token from the retreating player?
When the answer is yes (which I assume), do I place a second token? (I assume no)
"Courageous to the end" Action card: Are the two dice rolled considered "combat rolls" of the ship? I.e. are moral boost, race abilities (Jol-Nar, Sardakk Norr, Letnev) included that modify combat rolls? And can other effects regarding the selected ship be applied (e.g. Winnu, Sardakk Norr, Hacan & Lizix Flagship)?
"Research Team X" Agenda card: If the elected planet has already a tech ressource, does exhaustion of this planet allow ignoration of two tech requirements?
"The Crown of Emphidia", "Shard of the Throne", "Holy Planet of Ixth" Agenda cards [uncertain]: Does the player having this card lose the VP in case he loses the card due to other effects (Judicial Abolishment, Miscount Disclosed, New Constitution)? (RAW say no).
Warfare: The secondary ability allows production with one space dock, the rules (88.3) say that Warfare secondary ability allows production with one unit.
Nekros "Valefor Assimilator X/Y" race tech: What happens if the copied race tech is removed due to elimination of the other race (problematic with Muat and their war sun tech => it allows to Nekro to have a unit, but no tech on the command sheet after elimination; also what happens when in this case the X/Y token is moved away from the Muat race tech? Similar problem appears when the cloned tech is the "Floating Factory II" from Saar: What happens when the space dock is in Space, not on a planet and then the tech is gone?)?
