Me too.. and in general after opening a previous project.

I updated this week, started designing a thing and found that I cannot subtract objects after I have saved shut down and started back up. I can do simple subs but not the complex ones that "worked just fine" before I saved and shut down. Previous version had the same problem. I like this software, I was thinking about getting it but not if its going to be so buggy. I have a day in this design and now I cant do anything to it, even after having multiple project files to keep things simple. Window 10 64 I7 32gig 3tb 2080.... So frustrating.. Yes, I even lifted off the grid because most of the time subtract leaves parts if it is sitting on the surface. I mostly just want to add to the list of confirmed "subtract does not work properly" cases.
