I get this popup even though I didn't even subbed to this version, but to non-RNG, yet I don't shoot any vans, it can just pop randomly tbh

i understand mate, you did your best

I can't fix that without downgrading the mod, please note it, either you will have to unsubscribe from it or from other mods. Your problem is probably caused by my and some other mods being too detailed, hence engine have to create lots of things till its buffer's bounds are full, then that popup pops up I guess?

when i shot the van this message pop up on my screen saying to many index or something, after i press ok the game crashed, please fix

Ahh thanks mate ;)

There's one that just adds them as props, you can blow them up ofc and it's the one I ported it from. https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=2056339667

This a nice van I wonder if there's a mod in the Garry's mod workshop that makes them drivable
