However, if you log out and back in they start working again (usually) and, at least sometimes, it seems to work on both servers as long you've relogged once.
There are also times when it doesn't seem to carry over. Usually they do work on server1 but I've had an occasion when returning from server2 they stopped working.
Server update seems to reset this as well. Not entirely sure about normal server reset as it doesn't seem to be always predictable.
Talked about this with Endelyon on Discord but thought I'd put it here as well since it keep on happening.
