I'm unsure if this is another element of the issue, but I appear to be having similar issues joining a multiplayer server post-hotfix.   I seem to be trapped in an infinite loading screen which seems to be stuck on the "Recalling Buildings 100%" element. I've searched for similar occurrences and this seems to be one that's been lurking for the last 12 months. It is potentially game breaking and can spoil players enjoyment after investing so much time on a project.
