Multiple disconnects and client crashes after recent patch, that also close the map

Not sure what exactly causes them, but those are the latest logs. I tried to access map, got disconnect, and when reconnected map was gone.

This is happening every other map, sometimes more often. It's devastating, as you lose maps, map progress, and have to reattmept the same map without tablets or any side content.
