Fire shouldn't be allowed to go over any structures I believe....
I don't know if that has been implemented(with turrets and stuff), but my bug report is that my commander was occupying a fortress when fire overran it and killed the commander, which shouldn't happen. Is it possible that the fortress disappeared and the fire moved simultaneously, so I just didn't catch it?
Fire cannot destroy fortress. Probably fortress disappeared, and fire immediately covered you.
Hm, maybe I should somehow prevent it from hapening.
BTW even worse thing hapenned to me. When you are in transport, the fire is expected to destroy transport first (so the transport provides you 'extra life'). At least that's how I programmed it, and it works.
But it happened, that fire spreaded from some field and destroyed my transport, and immediately fire spreaded from some other field and killed me.
Perhaps I should also prevent it also.
