This thread is no longer important! The bug is known. When adventuring today, I managed to somehow delete an item I was trying to pick up -- I tried to replicate it, but it seems to happen at random (in two tests with the same items, it only happened one out of two times). It isn't guaranteed 100% of the time as I've found out through testing, but here's how I managed to do it sometimes: 1. Have an item on the ground (henceforth referred to as Item A) and an item in open inventory (aka clicking it and holding it out into the play area, see following screenshot; henceforth referred to as Item B). Demonstration (large screenshot) In the screenshot, the carnelian is Item A and the pear in my hand is Item B. 2. With Item B is active, click on the tile where Item A is. 3. Sometimes, you just drop Item B and nothing happens. Other times, you walk over and "pick up" Item A, but Item A is deleted and Item B remains in your hand. I haven't been able to replicate this reliably, but doing it on the occasional item has worked for me. It seems to work more often if Item B is a sort of drink (booze, not potion). PS: My only mod is 'death by a thousand taunts' which just adds monster quotes. PPS: My version is 1.1.2, the version that was released on Steam this morning
