(Good song by Dream Theater, by the way)
this Fortress was started on version 40.18 (no music)
I think I'm on year 3 or something, The current month is Opal, and after about 3 minutes of play time, the game will crash. It's done this to me repeatedly, in versions 40.20 and 40.21 (both no music) around the same time, it seems. I finally managed to keep saving until it's right before the crash. I think it has something to do with the months changing, maybe a bug caused by the militia changing orders.
