Tuplet bug?

I found this when experimenting with nested tuplets, and wanted to check in case it is a bug.

In the attached example, if I select the D and increase the note value in Insert mode (using Ctrl+Alt+Arrow), everything from the D and out are deleted.

Other strange things happens when Increasing or decreasing the note value by clicking on the numerics or dot.

Yes, I’m afraid this is indeed a bug: using the lengthen/shorten commands with notes under a tuplet doesn’t work as intended at the moment. It’s on our list of things to fix up as soon as we can.
