Edit - I realised the Future and the Past version of the Act 3 town are in the same map, if you go far enough North West over the void you eventually reach the Past version of the town. I could even see active players etc.

Could maybe have some kind of bug abuse problems with skipping act 3 entirely so seems like a fairly bad bug
