search google to many times for resolve by myself but cant find anything please some one here show me the path how to fix this problem

Collector’s edition just give you Sigmar statue in the taal’s keep entrance, 1 portrait and 5 cosmetics for first careers, didn’t have it??

You also get all the music and artwork in your vermintide folder wherever you installed it.
