Minecraft Rig Acting Up

Hi, I am making a Minecraft animation with a rig of mine, but I came across something strange. One of the arm IK controllers is moving by itself (even though it’s keyframed). Below are some screenshots:



At this frame (144), the arm IK bone is keyframed for this location. But when I go forward one frame,


It jumps up by itself. There is no keyframe and I’ve cleared the bone’s parents. Unfortunately, since the file is for a full animation, it is too big to attach as a download. Sorry.

It is hard to say what’s going on. Did you look at the Curve editor? Do you see anything unusual there?

I got it. I was trying to make something else in the scene cyclic but I must have applied it to the character as well. It was jumping back to its first keyframe
