Thank you all for posting solutions to my problem, I had a few chuckles over the responses :) Yes it is one of Stimuli's animation files. I've never had an issue with the morphs until this pack. I watched my custom built figure 'shrink' as the animation was played, I saw a change and thought it was my imagination until I slowed it down to frame to frame and watched how the figure slowly moved back into a basic V4 shape with changes done to the 'jiggly' parts within a few frames :) also removed mine and replaced them with the authors version, such as original figure had a mixture of Girl4 and the reference was gone, just a basic V4 in her place. I've posted a note to him but he hasn't been on to get it yet. 

On another note, how do you slow down/speed up an animation file? I haven't messed with animations that much the whole time I've had Poser. I kind of treated it as an area that was taboo for someone of my level of Poser use to dabble in.
