Been playing with my friend and yesterday everything was fine. Today however we ran into an issue where when he would try to join on me his loading bar would fill all the way up and then just sit there. We are both on PC, and we tried with the default Vulkan, and DirectX11 settings. I figured it might be due to leaving the game off in combat, so I finished the combat and he still had the issue, even tried taking us back to camp. So then he tried hosting a new game and I was able to join, but once we got to the first combat with the Imps, I could freely walk around the combat, but it was still like I was in the turn order, but I couldn't attack or end my turn.
To clarify further, he also tried to join on my solo game, which I have a seperate profile for, and that didn't work either. Same full-loading bar, but dont actually get into the game issue.
We are going to try again some more tomorrow.
