file won't save undo history

I’ve got a file that will not save the undo history. Or maybe its not loading it when re-opening, however the preference is set to save, and skip loading is turned off.

New files that I test to save undo history will work (like making a few edits to a sphere, saving and re-opening), and older files will also reload their undo history, but this one in particular will not. I’m saving and opening as project files, not tools.

I’ve used qremesher on this file, and it has about 7 subtools. I’ve opened it multiple times, made edits, saved (and the undo history blocks are visible when saving), re-opened, and there is no history on any subtool.

Are there any workflows that are known to break undo history when saving (or opening)?

None that I’m aware of. There’s a button in the preferences menu(enable saving) as well as one in the file menu(UndoHistory)

Looks like that was it! Didn’t know about the one in the file menu - thought it was only in preferences.

Thanks!
