I've got a strange twitch in my character's head when I animate her. This didn't happen before.
If I rotate the torso in any way, then adjust her neck bone so she's looking forward, she get a twitch instead of smooth movement.
Her neck bone is set to progressive quaternion. I've tried setting it to quaternion and euler, then redoing the movements from scratch in both cases, to no effect.
It seems to move smoothly until just before the next keyframe, where it does a twitch.
I've done these types of movements many times before in uMotion and I haven't encountered this before.
