Too many addons but not too many?
I always happen to have the weirdest problems with my game. Now, I have just tried installing addons. Works great! Like fantastic! I love it so much. My game works fine when I install 2 addons, but once I install that third one it just messes everything up. The game works perfectly fine with 3 addons, but there's a twist. When I go to spawn it, say "pavehawk," it says "invalid model" when i'm sure I did absolutely everything right. I then though "Huh, that's weird." So I just decided to do an LSPDFR patrol and none of the cars I replaced in my "paatchday17ng" folder show up. All stock vehicles. Yet, the i accidentally replaced the "bison" in my "x64e" folder and that shows up! What's going on!?!? I even tried installing the gameconfig file that allows more addons (i think thats what it was) and 5x peds and cars. So, summary; 3 addons, no addon cars or replace cars work. Help, please!
Use this or another to put your replaced and add-on cars in to avoid to reach dlc limit.
@DylanKortman Bro you need a decent gameconfig. Also you need to have a mods folder to stop the game overwriting any changed files. Look here for tips https://forums.gta5-mods.com/topic/50/info-about-installing-car-mods/28
Try this gameconfig https://www.gta5-mods.com/misc/gameconfig-xml-dilapidated (in openiv go to \Rockstar Games\Grand Theft Auto V\mods\update\update.rpf\common\data) and replace the gameconfig.xml with the downloaded one. Make sure you backup your old files though.
Oops just re-read your comment properly and you might have already tried these things Sorry if you have.
