Whenever I play against a Lunara their mana crystal that indicates how much mana they have doesn't look like it's in the correct spot, it's off to the side a little bit. It's happened when playing my hunter deck and against another one when playing my warlock deck. It stays out of place all game and my friend could see the problem as well while they spectated the match. I play on andriod and have screenshots of both matches.
We are aware of this issue. Thanks for the report :)
This has happened on mobile for a while.
