The keys are getting split with move on any of my existing projects. Particularly a copy of the torso key is left behind. For now I just delete them (not sure if it is safe).
But working on existing projects is quite annoying, specially if you try to move multiple keys.
I cannot replicate that on new projects though.

Is anyone else getting the same?




UPDATE: Figured it out! Some tracks were influenced by newly installed Curve Editor!

The fix to the problem if you ever experience it:
Right click on the affected track > Curve Editor > Convert to Curve Data

After this option was applied it turned gray (no longer can be selected).
So if it is available, then the track is affected by "split-key" effect as I call it.

I am yet to start using Curve Editor and figure what "Convert to Curve Data" option is actually intended for.
