Received error code from mesh server

Received error code from mesh server when attempting to get tile map for Northrend: Invalid session
Loaded new tiled mesh for map "Northrend".


This is the error I continue to get from HB w/e I try to start it... Just started happening today.. are the mesh servers down?
