I was putting some items into my shop from my inventory and didn't notice i had selected "Discard item" on my Zed Codestone until it was too late. That's not my first mistake made that way, there's a reason I mostly use quick stock for putting rare items in my gallery. If i had to lose an item worth over 60,000 np though, I'd rather have clicked donate so someone else could have it. It is irritating either way.
Edit- The drop down menu error that caused me to prioritize quick stock was when I used a ghost buzz MP on my royal kacheek. I didn't realize it was in 2018 and i didn't realize how long ago that was. https://tdnforums.com/topic/50314-oh-no/
