Private Mod Crashing

[DONDADON]

Hey Guys, Im working on a private mod of my city based on LA Mod, it includes new models, some script changes and map changes. Today it started crashing. What happens is: I load the mod, start freeplay, it works for a few seconds (i can see the map and move around a bit), but then it crashes. I do not recall making any big changes before starting it this time and up to now it has worked fine. Attached are my log files hoping someone can find the solution.

Thanks alot, Dondadon.

EDIT: Ive discovered the trigger to the problem, for some reason theres an engine model that causes it, if I use a different model on the same prototype its ok, whats wierd is that if the model is clean (without doors and wheels etc.) it works fine, but the moment i add children to it I get the same error. Any idea why that should happen?
