Some players have noticed they're unable to make purchases from Lohner's Emporium of Wonders, due to the 'Acquire' button being unresponsive.
This is commonly the result of the Steam Overlay being disabled.
You can enable the Steam Overlay by:
- Open the Steam client
- Click 'Steam' in the upper left-hand corner
- Select 'Settings'
- Select 'In-Game' in the sidebar
- Ensure the 'Enable the Steam Overlay While In-Game' option is enabled
- Click 'OK'
- Re-launch Vermintide 2. You should now be able to make purchases from Lohner's Emporium of Wonders!
