What you were expecting to happen, and what actually happened:
I expect to be able to examine hero traits and talents in battle. Examining the hero brings the spell to the forefront. Pressing left or right brings the hero traits or portrait to the front respectively. Bringing the traits to the front freezes and / or crashes the game. This happens both with your own hero or an enemy hero.
How often does this happen? When did it begin happening?
Update 9.3
Steps to make it happen again
Play any battle with a hero with a class equipped and examine their traits in battle.
This could cause a lot of losses in Guild Wars.
Edit: It also crashes if you view hero traits on the pre-battle screen.
