“Acquire” button is not working for me - when i click it there is a button click animation and sound, but nothing happens. And “dashing rogue” cosmetic isn’t on steam, only in game, can’t buy it. 
Is there any way to fix it?
I have to ask, have you tried restarting Vermintide 2? Otherwise, try the ‘Verify Integrity of Game Files’ option:
- Right-click Vermintide 2 in your Steam library sidebar
- Select ‘Properties’
- Select the ‘Local Files’ tab
- Select the ‘Verify the Integrity of Game Files’ button
- When complete, close and reopen Steam
