Hi snowytrees ,
Very sorry you ran into that 😥
We did see if restoration was practical for us to do here, but in this case the DB logs that would of allowed us to do so are past our retention period.
(I did see that you had already restored some)
That said, we have identified the bug and will have a fix rolled out. Here is what is actually happening in case someone catches this post before we roll the fix:
Deleting a bang from the More menu will remove custom bangs that are NOT shortcuts.
In other words, any custom bang that is in the shortcut menu (enabled or diasbled with the toggle), is safe.
We'll have a patch out for this ASAP.
