I think we may have found the issue. It was the Resource.lua not calling the handling file. So the game when it was named HELLCAT isnt in the stock handling so it was crashing the car for not having a handling script. I changed the arrangement of the Resource.lua file so that the handling.meta was the first to call and it seems to be working now. Thanks for all the ideas and help!

The handling file only has one spot to name hellcat along with the vehicle meta file only has one spot aswell.

Hey everyone,

I have a possible stupid question. I am attempting to change the handling on a vehicle in game. This is a addon vehicle that works fine with a default handling name. ie BULLET. I took the handling script for BULLET and put it in to a new file. I changed the name from BULLET to HELLCAT. I changed the name in the vehicle meta file aswell to HELLCAT for the vehicle in question. When i try to load that vehicle with the HELLCAT Handling file which is the BULLET handling line without all the other vehicles in it the game crashes. Can anyone tell me why?
