Xbox Can't progress - ground missing, excessive loading

AnDr1na, I had this same issue in Dock Town on the first playthrough. I tried a couple of ways to fix it, and one worked. I'm not sure which, but it did the trick for me. The connection steps are optional. It just helps with synching. 

Ultimately, I just opened the map and fast-traveled to another location, like the lighthouse. Then I went to the crossroads and traveled from there. I took a look, and I don't see much on our side about this specifically. I will try to find the other thread you mentioned.
