First of all, I've got to say - this is one of the best overhauls, by far.
Me and a friend have been playing it together for a few months now, and just can't get enough
Recently we've started a new game, when A17.4 and v2.1 came out, updated through to v2.11 Exprimental 5 mostly without issues, besides one:
I've started a Civillian + Laborer character, and have just learned the Mechanic class as well, completed the quests, read the Mechanic Mastery book (the red one), and... none of the Mechanic recipes for the Cars, Engines, Steel Wrench, etc. are available.
I have Salvage Operations at 5/5, but Grease Monkey at 0/2, could that be the cause?
The mastery is activated for sure, it displays a lock icon and "--" in the skill point requirements, so it's probably not that...
Sorry if it's a silly question and thanks in advance
