Technical Issue Duel challenge movement getting stuck

[Iris]

If I challenge someone and we're dueling and unknowingly I move into another player doing same thing I get stuck. At first I thought something was wrong with my keyboard but second time it happened at the end of the duel and directly behind me there was player in a challenge I was stuck on. Pls fix.
I didn't notice this before current patch.
Edit: Can moderator move this to bugtracker section. In my haste to post this I did this in wrong section. You can also delete this thread and I'll remake it in correct section.
