Sometimes on the Level Up and Arcana screens, the stats are shifted downwards with a large unused gap between you weapons and stats. It makes it so you can't see your stats. It seems random when it happens, so don't know how to replicate it.
I'm aware the stats get pushed off screen if you have too many weapons and passives, but this is different. This is a large unused space that pushes them off screen that inconsistently happens.
