I also got a minidump about 15 minutes in.
Of note is that I played almost the whole 15 minutes in 8x speed. The problem is a real-time issue, not a game-time issue, if that helps any at all.
In other news, the ships look great, the firing effects are great. Shame you can't do anything about the icons, though. I suspect that might be a LOT of work.
One last note: the Corellian Corvets still think they are the same size as the Cobalts they replaced, and they want to sit VERY close together. I don't know if you can change that or even if you want to, but I noticed it.
Please, keep up the excelent work!
