Thanks for the reports, I will forward it to our QA team to reproduce. Unfortunately, they won't be returning until next week, and if it's a bug it's likely on the client side which means we would need to release a patch to the store so that may take a while.
Just curious, have you switched team leader mid-battle in those cases? If it happens again, please send a screenshot to
support@playmage.com so we can better identify the issue.
