During a co-op 2-player game, my friend was the host, in the Saloon, pressing E on the keyboard (or A in a controller) to access options/dialogue does not function. We tried it when I was the host and my friend joined in my lobby / Saloon, and he also experienced the same issue. He depressed the E on the keyboard or A in the controller but it doesn't function.
Step by step of the bug
Step 1
Moved close to NPC / Option with the Left joystick
Step 2
Pressed the A button to open dialogue and access the Workshop (applies to all Saloon options)
