This was previously working before the recent patch update. But now when I preview a mission and after clicking on the dialogue to zone to the next map (which in my case happens to be a space map next) I get a disconnected from server error.
This happens on all my test characters - even the fresh one I created from scratch.
There does not seem to be a problem playing the map from the map editor and clicking on Play Map.
But whenever I try to preview the entire mission by clicking Play Mission, I get the disconnected from server error when trying to enter the space maps.
I managed to get it to go from a space map to an interior map OK, though.
I had the same problem when I used a custom space map. When I transitioned to the custom space map from another map, I would get disconnected from the server. This happened every time. I switched to a pre-made space map and I no longer got disconnected.
