Pendean, it still happens to me sometimes in 2022, too. I'm fully updated. I help with CAD technical support for multiple offices, and have had reports from it happening to several others in many different offices.
- I do not have a limited user account on Windows.
- Using Drafting & Annotation workspace, not switching.
- Not changing profiles
- QAT on acad.cuix file. I do have another partial customization file loaded, but so far it's impossible to test if that's a factor because I haven't been able to determine steps to replicate, and that partial is needed.
- I have added many tools, like COPYBASE, BREAKATPOINT, EXPLODE, Draw order dropdown, HATCHTOBACK, QSELECT, Find Non-Purgeable Items, and more. I have some custom tools, too, but they are added properly to the acad.cuix and shouldn't cause an issue.
The issue is that we add these extra tools to the QAT, and then one day open up AutoCAD and the QAT reverts back to unedited acad.cuix. But it's not reverting everything. I've also edited the tools on the ribbons, such as the Home ribbon, and those remain the same. Just the QAT reverts as if it's a fresh install. So everything we've added is no longer there. If your users are not adding extra tools to the QAT, they would never experience this.
It appears to be an AutoCAD bug. I've reported it, but I think it's going to be very hard for the Autodesk guys to fix until somebody figures out the replication steps. After these years, I still haven't figured out the pattern because I only notice it when I next try to use the tools, and I'm not drafting every day, myself. It's hard to remember what I was doing the last time I had CAD open. I think it's only happened to me once in the last 4 months.
If somebody has an idea of the steps to replicate, I will gladly test and confirm.
