If I added a player to a group using o.usergroup add ****** vip, then also used Timed Permissions to add him to the same group for 30days, once the 30days is up, will it remove him from the vip group, or will oxide permissions keep him there?

The plugin would remove him, as he can't be in the same group twice with Oxide.

Awesome, cheers.

could you send me the command you are using cause its not working for me trying to do the same thing
