Hello everyone, i just explored very annoying bug. When player for example with nick "test" is already joined on server and somebody will join with nick "TEST" it will let him join on the server, and when the original player (test) have set any PermissionsEX or GroupManager group, he will lose it and it will be given to the player "TEST" ok.. when player "TEST" will disconnect, original player "test" gonna get his Group back, but still.. it is very annoying, any tips to fix this, please?
