Hi, When I make changes to permissions or user groups, they are reset when the server restarts. Sometimes they save but most of the time they don't. Any ideas?
Sounds like your server isn't setup to automatically save at intervals else your server's filesystem is read-only.
Make sure server.saveinternal is set with your server and try saving manually with the server.save console command. If the above doesn’t work, then I’d suggest contacting your host.
