Inventory is gone....

I ran a T15 map and juiced it as much as possible.
I got in, started killing mobs, and then a Divine Orb dropped! I got really excited and continued clearing the map as much as I could. Eventually, I opened the breach and began killing the mobs that poured in.

Then, the game froze. I waited a little, unsure of what to do, and remembered that if the game crashes, I should be able to re-enter the map and continue. So, I pressed ALT+F4, restarted the game, and logged back in.

When I got back, the portals were closed. The map was gone. I thought, Well, at least I still have my Divine... Nope. My inventory was empty—everything I had picked up was gone, and so was the map.

This is absolutely breaking me right now. Farming is already so hard, I get one-shot constantly, and now, the one time I get a Divine Orb, the game crashes, and I lose everything. What is going on?!

Yeah... It's really crazy... I feel so freaking sad now.
