I just spent 2 hours making various animation, i tried to delete 2 nodes and instead the model with the animations inside deleted itself because the animation editor is trash at knowing what to focus on, all the animations are gone.
Expected behavior
I wanted the 2 nodes which i highlighted to be deleted instead of the whole model and i expected to click Ctrl + Y to get it back but nothing happened.
The Animation Editor is completely broken at the moment, it sometimes fails when attempting to select something, as you showed it fails to properly note its change history down, as far as I can remember; some staff said it was already ‘end of life’ despite being the only native animation editor.
