Hello, this is the first time I post something here and I feel kind of weird that it has to be a bug. But I guess it would not be good if it happened to anyone else! As I was going deeper into the mine, around 45~50 (the second chest after floor 40, I can't remember the correct floor), I found a chest with one Tundra Boots in it. My bag was full, so I had to throw something away. After some time thinking what could be spared to trash, I finally placed the boot in my inventory. As always, after I take an item from the chest, I click on it again for it to disappear. I wish I could see my face when I found out that there was another boot in there! I thought "Oh, that's probably a feature from level 40+. Twice the loot from now on". And so I measured what item would be worth of throwing away again. But as soon as I placed the boot in my inventory, my game closed. No text, no warnings, no good-byes. Nothing. I do have mods on my game but none of them changes anything of what was described here (as far as mod description tells). List of mods that I have installed:
