Perma Loading.... Black screen

Perma Loading.... Black screen when attempting to walk through particular tiles. Scary as hell when it first popped, as there was a bear right by me, or at least the minimap showed it. Using the minimap to move backwards I was able to relog and resume, then attempted to enter the area from a slightly different angle, same thing. Relogging the client while inside the Loading... area still kept the Loading.... black screen up. Only able to resume visible screen by navigating via minimap out of that particular map tile ... not so easy when in autumnal forest. Something on those tiles I'm not supposed to see hmmm?
