The radar thing isn't exactly a fix. We currently have a client crash that will cause the client to crash repeatedly. We know its related to the radar map, so temporarily we disabled the radar map opening on startup until we can get to the source of the crash.
This problem with the desktop settings getting wiped seems to be a side effect of this change and was not intended. We are looking into it now.
Just so you know, I don't think that's the case at all. I had the crash thing happen to me a few days ago after placing a boat. Everything was fine, placed the boat, crashed. Couldn't get back in. Logged out of 2D, into SA, walked three tiles away from the boat, logged out of SA, back into 2D, and everything was just fine.
The radar map "may" be part of it, but if that's really the case, shouldn't I have crashed again when I took three steps back toward the boat?
