I am experiencing this also, but I know why it is happening.
The area you are describing is "between maps" and when Rythal did his fix he didn't have mop to test it with.
He also treated the Vale of Eternal Blossoms as a city, when in fact it is like a mini dungeon or sub area.
Now that the source has been released, I recommend making the best of it and waiting for the next version of carb...
I can see many fixes coming in the near future.
