Oh actually I figured out a way to solve all the problems with missing models for peds, vehicles and bodyguards. Simply download 2 versions of the mod, one is the newest version, the other is the oldest 0.7 version (Nov. 18), and delete the lst.ini in the new version, and drag the lst.ini from the old 0.7 to the new 1.1a files. then just drag the edited new 1.1a files to the game root files, launch the game and shit should work out.
