Any further on this, seems like you have identified it. Found a mod that provided a modified gameconfig.xml allegedly adding 100 more add on cars. With all the police models out there, and associated public safety, it is nice to be able to have additional. I find the vehicles.meta for mpchristmas2 stops working if it goes over 121kb, and that usually has me right around 19 cars on that. However cars added to mpluxe and other locations don't cause the crash. Where is the best place to add cars on? Thanks a lot, still pretty new at this but learning quickly.
