IllegalArgumentException: A team with the name '998team-68' already exists!

Reported by @nytedemon12 on Discord

Sometimes this error occurs although there is already a check if the team exists (but maybe the wrong way)?

The code: https://github.com/Xitee1/PowerBoard/blob/cfbf67a0986e3a85f17a483c4d500e64125b811e/src/de/xite/scoreboard/modules/ranks/RankManager.java#L136-L138

The error:

I've just got this issue myself. Seems to be related to server crashes / no proper shutdowns.
