issue with vitruvian bones creating random keyframes

[jonathan.reaux]

Using version 14.2 on windows

We keep running into an issue where Moho creates a bunch of random keyframes whenever we use vitruvian bones on a character rig. If we don't switch the vitruvian bone, we don't have a problem. But once we switch a vitruvian bone to another bone in it's group, moho will sometimes create a bunch of random keyframes all over the timeline. It is completely random. Sometimes it does this error and sometimes it doesn't. It happens to all of our characters that have vitruvian bones. Sometimes it happens when I try to copy keyframes, or drag keyframes. Sometimes it happens when I try to make new keyframes. It's never consistent, so I can't tell what's causing it, other than it has something to do with vitruvian bones, because the issue doesn't start until I use them.

Check out the below video to see the problem...

Here is one of our characters if you want to try and recreate the problem. There are vitruvian bones for the feet.
