Was cutting and pasting another compilation together and in the process of [Click album]->[Triple-click lower tabs field]->[Ctrl-V]->[Rinse-repeat].
I mistakenly did Ctrl-V before changing out of the album (had clicked the title field). When I realized I had pasted the wiki URL into the album title field, I said oops and hit Ctrl-Z (Undo). The field went blank. Ended up typing it back in manually from the CD cover…
Second time this happened (an easy accident when you have to repeat the above process 224 times to get all the album info the same between tracks on a 16 track album :shock: ), I tried Edit->Undo, same result.
