"You cannot claim this city because you do not own some of the content used to create it."
I can't seem to join any regions with open cities because of this message. I bought the standard version of the game but I just can't find any regions that were made by someone with the same version.
There seems to be no way to filter for regions created using a certain game version (or even regions with open spots), which makes finding a region to play completely impossible.
