Weird persistant animation on bone

This character has a weird, small animation when I scrub the timeline and I can’t find the keys for it.
The chest bone just rotates a bit when I am trying to animate, and this gets included in new actions.
Any ideas how I can find these animation keys?
The rig is a legacy one, from another character if that helps. There are some cruft animations to clean out, but I don’t see how the short, problem animation can propagate to new actions.

No blend file to look at = no replies, we cannot see your desktop from our desktops, so have not the slightest idea of what could be wrong :slight_smile:

Cheers, Clock.

Try to select all bones and see if anything appears in the dopesheet

Ok after deleting the actions the problem is gone. Thanks for the replies.
