Rig is randomly moving? in a pattern? when there is no keyframes regarding the pattern?

Please watch this video to understand what I mean

How do I fix this?

Thanks!

Can you put in a blend file. Post here if you can’t post yet and give us the URL.

There are places outside the dopesheet where animations can happen.

For example, certain modifiers (I know off-hand only the build-modifier, but there may be others, so check the modifier stack, just in case).

Or, if you write “#frame” in any number field.
