I noticed this too about a week ago.
Also, I can no longer manufacture a project without saving it. Sometimes I'd run a face routine for a piece of stock I'll never have again (it was recovered waste material) or I'll just make a quick update to something I've already manufactured but do not want to change the original document (actual example: I decided I needed to extend a lip on a clamp a tiny bit to better fit a taller stock than I normally have. I secured both clamps to the table upside down, then ran three passes with a tapered mill in a rectangular shape to achieve this.)
It does appear that I can modify setups and add setups in existing documents without downloading the machine again.
Is there a way to avoid the forced save?
