After a day of using, closing and opening the program, my avatar settings were reset. How to recover? The program interface is inconvenient and unintuitive!

What are the ma0.avc and ma1.avc files? Why, when adding a second avatar and deleting it, it does not disappear immediately, but becomes darkened? I deleted it and don't want to see it again.

But, most important, how could this happen that after the program was closed, the settings of my avatar, which I used before closing and didn't change the settings at all, the avatar settings were reset? Instead of my avatar, there was another and now I have to configure everything over again.

Saving settings is indistinct and, as it turned out, useless. It's easier and more reliable to make a copy of the entire Documents\Holotech\FaceRig folder. Sucks!
