My toribash crashed while i was in judo tourney. and when i relaunched, the other me from the crashed toribash was there. what's wrong this time

That happens when you ping and reconnect.

The other duplicate goes away in 30 seconds or so, so it's nothing to worry about.

30 seconds!!! the other one lasted for 5+ minutes!!!

You may be exaggerating a bit there, but it depends on how hard the long was, I guess.

Still nothing to worry about.
