Are you perhaps using starch? Two pins in specific positions next to each other? Pins only moving one way usually are an indication that you have created a "super-rigid" region somehow by placing pins in an unfavorable pattern. That is in terms of the underlying algorithm correct when it tries to avoid overlaps/ intersections, but naturally will not always be desirable. Hard to say more than that without seeing the project...
Sadly no starch pins are being used.
I started work today and tried going back to a previously okay version of the comp and now that comp has been corrupted as well.
I'm going to see if I can get a screen capture of what I am working with so it will shed some more light on the situation that is hard to describe.
If you email me the project, I'll have a look. My address is

I still think you have an issue with teh deformations accumulating unfavorably, so I second Todd's suggestion of sending the project. I also noticed from the video, that everything seemed ratehr low-res, so you might consider to in fact use a larger version of the creature and then scale it down after you have animated it. I could imagine that because of the smallness, you might cause internal math errors, where AE can no longer keep trhe folding of the pixels straight. You can only stretch a pixel so far before they break, if you get my meaning....
Thank you both.
I did send Todd the project file.
I had previously been working in a much larger format of the creature and it lead to slowing of AE and the computer due to the size so at the start of this current episode I decided it would be good to keep it smaller.
I have currently recreated the project from scratch and things to be coming along alright but I'm still concerned that this could happen again.
Let me know if you come up with any ideas after seein the project.
I'll have a look at the project today.

Well, that certainly is a fascinating bug.
First, let me give you a couple of ways to make things work:
The bug only seems to affect dragging of the pins in the Composition panel. If you drag the pins in the Layer panel, it works OK. So, if you dock a Layer panel next to your Composition panel, you can finish your animation that way, dragging pins in the Layer panel and seeing the result in the Composition panel.
Also, it seems that this isn't related to where in the timeline you are, but where in space the body (your master layer to which the limbs are parented) is. When the body is way to the right, that's when things fail.
Rather than wait until I've got things perfectly isolated and well understood, I thought that I'd send this update to give you some clues about how to continue with your work. The next step is for me to work with one of the testers to determine what's _really_ going on.
Thanks for the response.
I did a new comp and matched it to the last frame of the corrupted comp so I could continue animation.
I will try using the Layer window if the problem occurs again. Though it will be strange to be pushing points not directly on the character.
