I don't know if this has been said yet, but there's a bug at the arena (i'm having multiple time in a row now) where you're forced to wait 2 minutes and it immediately skips to the bear trio.
Once beaten, you have to wait an additional 2 minutes which will probably lead to another skipping. But since this doesn't let you have any paws you can never win.
Let me know if this is only my issue or if it's a general bug
