Got a really weird bug; I buy one of my own custom ships at a cost of 42720 bc. I launch it against pirates that destroy it in one turn (fleet has missile damage of 522). My Treasury reserves go down to -21921 bc. I am reportedly making 1096 bc/week. After one turn, when the ship is destroyed, I am back to +684 bc! Happy to send the game state to the developers for debugging if I can be told how to do that.
