While testing OCS, what's the funniest or most interesting bug you've encountered?

See, now you've said funny, all I can think of is crashes. There's been fun ones where you're trying to catch an AI who's decided to run away from you. I think this was earlier on. So he's in range, flying away, and you had an issue where he would reach outside of your streaming window and he'd stop. So then you'd catch up, and eventually you'd get the updates from this AI and he'd fly a bit further, because actually he's even further. So you're constantly having this little stop-start race against the guy, trying to catch up, and you don't even know where he really is.
