Vector moves everywhere for no reason

[JumboCracky]

Okay so I am currently struggling an annoying and seemingly-unfixable glitch where the character moves all over the place and I don't know what exactly it was that I did that causes her to go wacky. This is what it looks like:

Pretty spooky...
What kind of switch was it that I enabled to get her to act like a demon spawn? I mean, I could use this effect if I was making a horror cartoon, but that's not what's in my desire right now.

Please disregard the fact that the character looks undressed, but I was planning to dress her up later only after the thing is resolved. : /
Edit: I found out that I have a setting stuck on something because possibly when I add things "after" I changed that setting, that's when the wacky movement takes effect. What setting might that be...?

you have defaulted to interpolation mode "noisy".

easiset way I've found to cure this is to

>> set default interp mode smooth

>> animate / consolidate layer channels

>> go through layer by layer and right click on the keyframe at frame 0 to set "smooth" interp

>> animate / click again on "consolidate layer channels" to clear the check mark

I racked my brain trying to solve this myself. You are the man.

I agree with neeters. Thanks for that useful tip.
