I have this plugin installed on my server but when i try to assign permissions it tells me the permission does not exist. I tried the permission for all vehicles and tried doing them indiviudally but still tells me the permissions dont exist. What am i doing wrong?

Sounds like you do not have the plugin loaded. Make sure your are fully updated with Rust and Oxide, and check your logs for errors. If you see an error, you are outdated with Oxide.

Thanks Wulf. I have the plugin loaded and evrything is updated but ill double check everything again ;)
