Did I get auto-upgraded?

Strange behavior from Cura this evening:

I started it up by double-clicking an .stl file, like I usually do, Comura Articulatum from Thingiverse, and Cura launched like it was a fresh install on my laptop!

It gave me some quick hint windows, a little welcome to Cura and made me choose a printer. Thankfully, my Aurora A3 was still in the list - whew! But it came up in 'Simple" setup mode (I never use Simple mode). So I switched to 'Advanced' and all the settings I had made visible before were gone :(

Then I noticed I had 2 Aurora A3 Printers in my 'Printers:' selection. The second was set for ABS (I never print in ABS). So I removed that one.

Went in and re-enabled all the 'Setting Visibility' items and AFAICT none of my presets were lost: speed, infill, raft parms, etc. and even my custom print bed .stl still shows.

Oddly, the version still says 2.1.2, so if I was auto-upgraded, the version number wasn't changed.

No harm, no foul. Just odd and a little worrisome for a moment.

Does Cura auto-upgrade now? Or did it just lose its marbles this time?

Ok, I think I got the answer to my primary question: I did not get auto-updated/upgraded. I just now restarted Cura to make sure all the settings where still there/correct/etc. (which they were) and got a little window says "A new version of Cura is available!".

So clearly I was not upgraded....so what happened that caused it to forget everything and act like a fresh install?

puzzling....

There is no auto-upgrade in Cura.

The only thing I can think of that causes this is some sort of data corruption on your local system. At that point it can't find the machines / profiles, so it asks you to add a new machine.
