After a huge number of dry weather laps with no issues I have started to map some wet weather (puddles) to a model and have constant core.exe crashes.
Using the M2 bike as mod bikes appear to core entering the track...
Whenever I try to leave the track to return to pits or switch to replay cameras the game crashes to desktop, in-game crashing (just a low speed lowside) the bike appears to have a pinball effect on the physics with the bike flying off as if it suddenly weighs nothing, after this I appear to have no traction whatsoever with the bike just spinning the rear.
Off track grip is also hopeless with the rear just spinning even with barely any throttle.
