Undo and Redo sometimes picks another mesh

I’ve noticed this when working in Valence for say an hour or more is if you are working on a new mesh and select an undo it will undo the previous mesh you were working on. Hard to reproduce but I’ve see this quite a few times. I’ll have to save, close and reopen to get the normal behaviour back…

Oh no. Thank you for pointing that out. I’ll take a look. If you can reproduce this with a few steps please let me know. Undo / Redo is complex and I’m always trying to make it more robust.
