Just sent in two bug reports about those. When I say the library I meant Mr. Harris' study room. I've heard other people say that they just talked to Simon after defeating the imperials and that gave them access, but I have been trying to talk to him over multiple loops and the only thing different from the start of the game is that talking to him chopping a tree will pop up a message saying something along the lines of "I should talk to him in different scenarios, this might take multiple loops to figure out."
Thanks! Status is already fixed, that's in the next update hopefully this weekend.
I'd love to have a better way to display skills, but there are limitations on how that's handled in RPGMaker (one of many reasons I'm moving away from it after this game). I've already done enough breaking the system, in trying not to do any more (Fire and poison DoT being typed, resistances reducing damage by a percent, everything about toughness and walking skills, etc)
