Hello, I am one of a group of a 3 friends. We are also experiencing this issue with one among our group. He was able to play perfectly fine before the update, now, afterwards...
If he hosts a game we attempt to connect to him go through the usual loading process and then I find myself on a screen that says 'installing' the progress bar is frozen at 0 and it never moves no matter how long I give it time.
If we host and he connects... on his end, he gets stuck at 80 percent just as the above fellow mentioned. We have made accounts on the forum to upvote this post for visibility please respond we need your help oh great Larian overlords so that we may once again embark on our journey...
