I upgraded SU2021 Pro on two separate machines and have been modeling over the last two weeks with them.
There have been multiple occurrences where I have lost entire days worth of work because I’m hitting save all day long and do not get any error messages, but when I look the next day it is gone. There are no read only errors and I thought I was going crazy at first but I literally keep making the same edits over and over to find they are gone the next day and timestamped before I started even working on it. What the heck is going on?
