Stop lights from moving during animation

This is driving me nuts. I have a scene where the spotlights are just right and I want to add dforce hair to the mix using a simple keyframe animation to drape it. Problem is the lights move for some odd reason and are all out of position on the final frame. Since you can't freeze dforce and go back to frame 1 like you could do with dynamics, I have no solution.

And you're absolutely sure you didn't accidentally create keyframes for the spots on the last frame?
Wait what? You can freeze the sim and go back to frame 1!
I would save your spotlights as a light preset and run deforce with out lights add or apply the light preset when your ready to render quick easy and reusable
eidt i do the same thing for HDRi lights for some reason they move as well
Really? That's funny, haven't have that happen to me yet?
Yes I have yet to figure out where the added keyframe is hidden that makes the lights move. after you run the deforce simulation an hdri's does not show up in the Daz timeline or animation 2 to locate the keyframe associated with the movement ,.so I have no idea where you can find it . so save the lights as a preset and removing all lights before running the deforce simulation was the easiest work around for me
The issue I have is rendering a 30 plus keyframe deforce animation and have it keep crashing on save. the only thing i can contribute it to is running out of vram and when saving the gpus becomes overwhelmed I have 2 titans each running 6 gigs . so at this point for me using deforce in animation is not possible.
Hey,
Was this ever solved? My lights are roaming on my aimaiton as well.
Thanks
One option is to select the lights, right click on the Parameters tab, pick Clear Animation->Clear Selected Items(s)
Hi go and grab the "freezethings"script

An explaination of its function by the creator here:

Probably a stupid idea but how about parenting the lights to the camera you are using?
