This is really fun so far!! I haven't completed it yet, but I got this error message after choosing my specialty. Hasn't seemed to effect anything, and I'm pretty far in, but I figured I'd share it.

Thanks! Glad you like the game.

I just wanted to let you know that I just encountered this bug myself but at a slightly different time. For me the bug popped up as soon as I finished the "Get Emmitt to 30 music" quest. Other than the difference in timing the bug appears the same. This is with the current beta version v0.852 which I found on itch.io using a Win7 SP1 os.

An exception has occurred.
While running game code:

Thank you, I believe it will be patched this weekend.
