I am having the exact same issue on my Zealot Preacher. My first character created was the Psyker who does not have this problem. My third created was veteran which also does not have this problem. The Zealot was the second character I created. I wanted to add, I am beta tester and pre-order beta tester and have the imperial edition, owner of Vermintide 2 and Vermintide 1, all games on Steam.
