I was working on just buying things, and I got to around -235 bc. I then went in to the shipyard and made a new ship. I go back into the map, and my money is at -22354 bc! That's about where I started before I started buying things, but it had been in the positive. I don't have a debug.err or a save (the auto save happened the turn before). I just thought something was wrong and I decided to post it.
