The only thing that happened to me was the bug Medusa already described in her earlier post: Loosing energy throughout the whole race and getting the "wrong way" message all of the time. The message apperaed even when I turned my ship around in that particular race and flew a backwards for almost a full lap. Happened only once to me until today,though.
What I did experience in last nights' races a few times was that the game suddenly froze completely at sometime during a race and after 1 second everything was ok again and I could carry on with my racing. Weird stuff. I also met GOD_OF_LORD and his everlasting turbo boost in one of my races about 2 months ago, but as we all know that is no bug...

Btw. does anybody know a player called "HorstFeratu"? I played against him online a few races last night and he's pretty fast (without using any cheats).
