Unit from "clone army" stuck on board

Fought a clone army (not actual player). Not sure if the Warwick died or not (was running sorcs, so he might have been deleted), but I got the "win sound" and the Warwick was left on the board. After that he was stuck for the rest of the game. https://imgur.com/a/m9UjYy8 https://imgur.com/a/E2Rc5xe
