Rolled back map and loot upon disconnecting

So, this happened to me twice already in the past 24h and it's getting rather annoying.

What happened?
During what are seemingly random maps I'm sent back to the login screen with a disconnected from server message.
Upon logging back in, all the portals to the map I was running are gone and ALL the loot I gathered in that map is also rolled back (basically deleted).

This is not the loot of the last few moments before disconnection that is being removed, the whole loot from the whole map run since I entered in the area. Meaning even several minutes of farm, like the first time it happened where I lost all the loot from the Breach Fortress as well (including stored graftblood).

Please look into this, it's just gigafeelsbad here.


Follow-up:

After writing this post I got back to the game and tried to re-run the map and now I'm hit with this:



Edit:
The map I tried to re-run was not even, in fact, the map where the rollback happened, because I lost that map entirely.

My friend has same issue, crashed twice in 10 min, he plays on Stockholm server.

London and Milan gateways, got rolled back twice while trying to run a map around 10 minutes ago. Also lost almost a full stack of sulphite scarabs from my map device.

Also got multiple instance crashes aka losing map and loot today.
Yesterday there wasn't such problems.

I'm bumping this as it's still happening.

Server disconnections rolling back my progress and deleting my map.

Just got hit by the same issue, a few minutes after a friend of mine lost 6div in a map because of the rollback.
