I set my street to Lost Woods yesterday. I noticed today that the "Return Home" button in the iMG cloud shows Crimson Forest as well as when I bring up my profile page, it shows my street as Crimson Forest.
This same thing was happening to me, but it eventually fixed itself after a while. I'm guessing the game just needs a little time to catch up with itself to update things like that.
I am having the same issue. It usually happens when I try to return to home street from a friends street. It reverts back to the reset street we got at the change over.
Well it's been 24 hours and it's still the same. If you look at my profile and then view my street from there it's the Crimson Forest with the red leaves or hearts on the ground, but I have the Lost Woods.
