1.09 takes everything from 1.08 made by Phantom + adds objects. I know Phantom did not list all the objects from pac in txt, probably he thought modders will fix it.

It is possible that composed objects use some objects from 1.09, so compiling mods will create doubles. Those mods are more of a database, each modder should pick from what he likes, then create his own pac. If I have time this summer, I will try to remove the clones from both mods.
