I found a bug and i could it also reproduce on a clean GTA V and lspdfr installation, basically you just have to go on duty in a police station and then off duty and then again on duty and lspdfr will crash, until now I just can confirm this in the DownTownStation, but I think its true for all stations or the general on duty, off duty process.
Yeah about that not true, so my question again: Does anybody know what the changes to the vehicle.meta file are, so I dont´ have to overwrite my custom file.
