@Timdy I FOUND A SOULUTION!! So.. The only way that I found out that will work, is you have to downgrade your gta to an older version, I downgraded mine to 1.0.2060.1 and it seems to be working perfectly fine. Go try it for yourself and tell me if anything is wrong or if it indeed does work for you too

@Timdy Yea, I'm sure a lot of people do since this has over 600 views, I have no clue what's happening, might just try and download an older version of gta if I can

Please, you guys need to help me! I've been trying to get my gta to work with more than 4 addon vehicles for 3 hours now and absolutely nothing is working after the new update! I had almost 50 addon vehicles before the update and it worked perfectly, so I'm very confused as to why it isn't working.. I've already changed the game config and added the heap adjuster and the packfile limit adjuster and everything, even went as far as to boosting the limit amounts in the heap and game config. I have deleted my mods folder and retried everything already so any help is going to be needed! Thank you guys!!
Edit: If you need anymore info, just ask and I'll try to supply with the answer.
