Found two pieces of Errata so far In this game.
One is on Preston Garvey, (unless it's weirdly intentional) - it says he remains if the vault 109 and vault (sixty something - if have to go check to see what number but I know it was in the 60s) decks are not in play. The only two vaults in the game and only decks for them are vault 109 and vault 84.
The second is one of the quests for the Commonwealth scenario. Can't recall which again without going and finding it but it has flavour text that is obviously from the aliens questline and not the synth one which it is meant to be.
The only other thing I've found is with the Far Harbour questlinr. As far as I can tell the game gives no rule as to what to do when all the faction tokens of a type are on the board and more are meant to be placed and some quests rely on one being placed. On the same line on this scenario, if the quest is completed by the end of turn mechanic placing a fog toke who gets the xp? Since from what I could see there is no way for a player to place more fog.
