Clear scoreboards on server switch

[andreasdc]

Feature description

Players get kicked when you connect to the server with the same scoreboard names.

Goal of the feature

No kicks.

Unfitting alternatives

Tried setting unique names, but to achieve full protection you need to do it everywhere.

Checking

• This is not a question or plugin creation help request.
• This is a feature or improvement request.
• I have not read these checkboxes and therefore I just ticked them all.
• I did not use this form to report a bug.

It creates huge problems, even with many checks to have unique names
java.lang.IllegalArgumentException: Team 4168557420428d7f already exists in this scoreboard

Currently I can't even join the server, it shows this error.

Remove all scoreboards and scoreboard plugins. You likely have a broken scoreboard plugin

I sometimes get kicked when switching servers, are you sure that it works properly?

I don't know - create a minimal reproduction (two new vanilla servers with same scoreboard names) and see
