Hi,
Great work on the game by the way. I love it. The bug I would like to report is minor and please accept my apologies if it has already been reported (I tried a few searches but didn't find it). Anyhow, after an evil race was destroyed all their ships became pirates, which is pretty cool. However, I found that after I destroyed some of these ships, they would still show up on the screen. I could drive right through them and they would not move or do anything, but it was a real annoyance because I had to always remember which ships on the screen were really there and which were not. I assume they were not meant to be ghost-ships as there was no spooky music and no affect on my planet's moral:) I have only had this problem once so far, but thought it was worth mentioning.
Thanks,
