Is this happening to anyone else?

I’ve been using Nova Skin for YEARS and have only now made an account. The reason why is because I didn’t want to. “Why not?” Because the skin editor is glitchy and sucks. Spent like 15 minutes on THE HEAD of a skin just to ctrl+z (undo) and for it all to just be gone??? wtf??? why is it gone??? It’s legit pissing me off because every time I use Nova Skin I have to try to remember to stop using ctrl+z to undo and just use the button because it resets the whole damn thing, and its freaking annoying. Trying not to swear because I don’t really know if it’s allowed on here. Does this happen to anyone else?
