can't undelete deleted notes

I have a problem I don’t want to reproduce :frowning:

I selected two notes, right-clicked and chose “merge”, then (I think) hit enter. I now had a note on top of those two that just said “New note” – so I hit delete to get rid of it, and all three notes vanished and could not be restored with control Z.

Normally ctrl-z works fine to restore accidentally deleted notes.

This is on Windows 10, 64bit, and Scapple – no updates available
