Parts are being deleted when I try to make them local?

I'm trying to make some parts become local parts by setting their parent to a camera named 'LocalBin'. however, once I attempt to do so it always errors with the error message below, deletes all the parts in the folder, and then moves the empty folder into the local bin. Why is is deleting my parts?

"Something unexpectedly tried to set the parent of Local to NULL while trying to set the parent of Local. Current parent is LocalBin."

(This is done from a localscript in the character)

Update: I found that if I move each individual part into the camera instead of the model itself, then the parts show up locally. However, now all of the meshes in the gun have been deleted, and all of the unions just look like big blocks)
