Ok ... So my monthly income was actually almost 4 million less than my expenditure after building some stuff, but I had slightly less than 4 million on hand, so it I only had to sell a little surplus junk to make it to the next month. It would be nice if there was a way to see how much you are in the hole without having to pick up a calculator, and perhaps a message saying why the game ended. Also, at one point I was seeing weight limits listed in the pre-battle equipping screen, but I'm not seeing them anymore, I suppose that was from a mod, but it seemed appropriate to have it.
