Map glitching at the Grymforge?

[cokoit]

My map in the Grymforge area is unreadable. It seems like some sections of other maps are overlapping each other, and at some point when I opened the map I saw it load a section on top of what was already there, as if stacking on top. I don't know what's causing it, but it's making navigating this whole area an absolute pain in the ass. Does anyone know what's going on?

Me too. Any fix?
