When I logged in today there are a ton of different players that I have never seen before and many more people with Great Buildings then I remember. Did we get merged with another world? Did I hit a level that revealed other players?
Thank you for your inquiry. I can confirm that Langendorn has not been merged with any other worlds. However, it is more than likely that the player base in Langendorn has increased and the players within this world have developed further which in turn has led to a steady increase in the number of Great Buildings.
While worlds will never be merged, this morning we had a neighborhood merge, which happens every two weeks. Sometimes you will not be affected by a neighborhood merge, but it sounds like you were indeed put into a neighborhood with different players.
