When I play the campaign after the first couple of days, whenever an enemy invades me, during the battle itself, the AI and the weapons seem to freak out. Guns, explosives, and debris simply goes through all the actors and ships and stuff, doing no damage. The AI also seems to mess up, and start moving erratically and firing everywhere. How do I fix this?

This is a known issue with some of the levels. We'll try to get it fixed for the next version. Sorry to hear that it's causing you problems.

Is it on Data's check list? I certainly hope it is, those get solved extremely fast.
