Game just stopped gaming in a waypoint and I lost all its progress

Hi,

Nor the first time I get disconnected from a waypoint map, but this time it was weird, and impactful to my progress.

I used a nice rare waypoint with goof affixes to do the map "crypt" on the far east (first one I saw with 4 affixes : boss, delirium, altar and breach), ready to do an amazing hard run !

But as soon as I encountered the breach it ended the delirium, started breach and a few seconds later the game just stopped. Everything was still "active" (no movements but fire was burning, effects were moving, etc ... music was still on) but I couldn't do anything at all (could open the menu though).
After a while I had to alt + f4, hoping my map would still me open when I got back.

Unfortunately not only it was not, but all the loot I got from it was gone from my inventory, and on the atlas the spot was "used", so the 4 affixes were gone ... so was my waypoint.

I know I won't get anything back probably, but this was quite impactful so I thought I would share it so you can look into it.

I did not know to use /bug while the bug was happening so I did it after I logged back in, don't know if it is usefull at all : 2 800 877 754.

Kindly.
