Hi, this was, as the users have pointed out, an issue with the folder names on Epic not matching up which had a fix go out on 10th November.
For the posts since the 10th however, we need the user's to confirm, (A) that they are on Epic and (B) if the issue reproduces after checking the game & Epic are up to date.
If so, then this may be another issue and we'll need a new thread to be created, thank you.
