Disconnecting and losing progress

Hi,

I have disconnected a few times today and I have noticed I am losing all progress I have made i.e. xp bar going down/losing items/losing waypoints/checkpoints I have obtained. I got half way through the Black Chambers, disconnected and joined back outside the door to the Black Chambers.

This is a major issue as if I disconnect I have been playing for nothing.

Thanks

Happens every 2 maps or so for me as well. Then when you reconnect the map is gone. Just lost my 1st unique map to disconnect, no death just login and all 6 portals gone and atlas shows map failed. Unplayable atm. I'm done.
