@chonkie Hey! Thanks for the response!
Sadly I already tried this; I added the cars one by one and after a certain number, no matter what car I added, the game wouldn't launch.
Currently I'm playing the game with those 23 addons and it works fine, but if I add a 24th it'll blow up in my face.
Your response did give me a new idea though, I'll try it out and I'll explain if it does work. Thanks again!
