The body.001 is the object I'd like to animate but it moves suddenly from one keyframe to next, and sometimes doesn't even move at all when scrolling the timeline.
You can clearly see the timeline cursor at the beginning of animation:
I've checked everything I can think of including:
- Making sure all the keys are not straight lines in graph editor
- Parenting to armature then animating
- Deleting NLA tracks and again adding one
- Not using NLA tracks at all and just using Action Editor
The body.001 can be appended to other blend files and animated without any issues
