I'm having the same issue + the server doesnt let the players in because of this. Fix please

[Andre601]

Something won't just stop working out of nowhere without changes, so you made a change.

Please share your server type and version. OP, please share server type.

[Andre601]

[PirataGu]

Functionally it has no effect, I haven't registered any yet. But just for information I posted it here, as you say maybe it's just the bungeecord doing it, functionally it's fine. Just to let you know for the future.

[SinestroCZE]

Anyway, I have to appreciate the quick response of the creator, a huge thumbs up for this. You are doing a great job, good luck in the future

What was the fix?

I will now close this issue to streamline the issue tracker. If you witness the problem again, feel free to create a new issue. I did make some changes to this in 2.8.7 and it might already be fixed.
