World map bug 1.6.

[raivoh]

In the Far East, this error pops up after every time trying to do anything in the world map.
This started after returning from Valley of the Moon and a Far Portal trip somewhere.
Tried saving and exiting game, then reloading character, won't work.
System is Windows 8.1.
