I have found what's causing it. Apparently when you enable "ignored by everyone" in menyoo, the police vehicles starting to drive like that. As soon as I disabled that option they drove normally again.

So this happens after I installed Vanillaworks extended

How can I fix this?
It also happened with "wov" before but I removed it before installing Vanillaworks.

Can anyone help me on how to edit the gameconfig.xml?
I get ERR_FIL_PACK_1 on loading and I have tried every single gameconfig available, so I figured I will try to edit it myself.

I'm looking for a trainer or menu script mainly for saving my add-on cars the way they are after tuning customization.
I am using simple trainer for all the rest but I couldn't find an easy way to save my vehicles on it.
Something like "Lambda menu" that FiveM has would work perfect!

Ok I have finally found the problem! It was the gameconfig file that caused that issue.
I copied the original file of the game to the mods folder and the game loaded perfect, so I've tried to download 2 different gameconfig files and the same one I had. The one I had did the same issue and another one crashed my game, then I finally managed to find a good gameconfig file that works and all my mods are in place.

Update.rpf and gameconfig got updated in the "mods" folder. I've tried to disable the RPH mods, scripts folder (which I had just one), some mods in the root directory and still the same.
Oh well.. going to be a lot of work but I'm going with fresh install and installing mods again.

@ikt I'm on the last version of the game 1.0.1180.2
Mods I use is for LSPDFR and I updated them, but I guess there is still mods that are not updated by the modders.
I use a lot of mods, should I list the mods that didn't get updated?
All I've tried to do is to run the game with clean version, without any mods, and to remove just the "dinput8.dll" file.
All the main mods, ScriptHookV, ScriptHookVDotNet and RAGEPluginHook are all up to date.

Thank you for your reply! So basically it can be any mod that causing that and not just files that are in the"mods" folder?

Hey! I have the same problem as you have. When removing "dinput8.dll" the game loads perfectly fine.
