YES! The world fix is for the routing issues only. It might have fixed a few other things too that were easy to fix like problems getting to sims doors and bath tubs. BUT this mod keeps non-playable sims from just deciding to move their houseboats. All those houseboats moving locations can cause serious lag. This still lets you move the houseboats of the sims you are playing, so it's a fantastic mod! And it won't compete with any other mods that I know of, for I don't know another that has addressed this issue before.
