It did a race with my mod, 15 cars on track, there where no problems during the race, but when all the cars where driving to the pit -> CTD, no error message, nothing in the trace file. So, where should I start searching for problems? I sometimes have this problem with my mod, but I don't know what causes it.
Now, it was a ISI track. This time the crash was after the race, but sometimes it happens during the race. Maybe a material/event conflict? The problem is it is very hard to find such type of issue.
