Animation in OpenGL finished but it is complete chaos in Render view- HELP!

HI there,

I just finished up an animation sequence, it is perfect and animates beautifully in the OpenGL view. When I render it as .png sequence, it’s complete chaos. When I view it in an render view - also chaotic. I haven’t used any effects. I’ve turned on and off the layers. I’ve doubled checked all the nodes and I’ve restarted the program multiple times… what could be the problem? I’ve attached screenshots of the problem. As you can see, the arms are all over the place, how can I fix it when in the Open GL view everything is perfect?
Looking forward to your help! Thank you!

Best regards, Sabina
