[Chimera-users] Saving a moved PDB only moved in a new session

It makes sense to me. When you save “relative to map” it means if you open the map and then all those PDBs they will be in the right position relative to the map.
However, in the current session, you have rotated/zoomed the view interactively (moving the map from its original position), and when you open the PDBs it does automatically apply all those other changes unless the map is the lowest-ID model. When you start a new session you haven’t moved the map around yet.
Here’s a more advanced suggestion that you could ignore (and I’m not even 100% sure it would work):
Maybe in the current session you can bring the saved PDBs to the right positions relative to the map by additionallly applying whatever transformations you had done manually to the map with the matrixcopy command. E.g. if map is #5 and one of the saved PDBs was opened as #6, it may work to use command
matrixcopy #5 #6
I hope this helps,
