Battlegrounds minion moving off screen

As I was playing, my minions over the course of a few turns slid off the playable area, to the point where I couldn’t reposition my minions on the right.
I can provide a screenshot to show the issue if needed.
I was late game Maiev, playing elementals

This happened to me just now. Do you have Mr Bigglesworth in your game? I think it’s associated with that hero.

its a graphic bug that occurs from time to time, restarting the client usually fixes it
