Here’s how I would do it:
In the default script of the frame, I added a “window.Removed_Pieces” variable & set it to 0

Then, in the code for the objects, I added 1 to “Removed_Pieces” when they get removed

& when trying to open a file, this happens:
I wasn’t able to reproduce this bug with another file, but it keeps happening with the file I shared in that post
thanks! it really helped
