having some replies form Max (scs team) and after I tested myself in ATS, it seems that lots of Ai models in traffic generate a game crash due to
out of vertex buffer segments but only in some places, respectively on newer part of the maps, while in old parts (San Francisco) there are absolutely no issues. this applies also to ETS2, new areas (DLC Italy, new Germany)
this is a brand new issue totally linked to 1.32 update, I am pro progress but this nasty bug don't let me think updating my ETS2 yet, hopefully will be solved in one of the next game updates before 1.33
so my recommendation for beta testers is to test ProMods in 1.32 with high traffic density and some more Ai traffic packs (like jazzycat Ai and trucks packs, painted trucks) only in this way you will identify possible areas with issues
