I updated the above link(LINK) again. It turns out the followSplineTrack() function of the Bot class can crash the game if unknown(for me) circumstances are met.
I used this function extensively; upon completing a lap all tournament opponents chose a new spline to follow if there was more than one defined, this sometimes resulted in silent crashes during tournament races. This error in the engine can still crash the game on tournament start but it is far too rare to properly debug and fix in the engine so this will remain a "half-workaround"...
