Installed "Pets" and cars stopped working

[radiophonic]

I realize Pets has been out for some time; has anyone run into this particular problem after installing it?

Sims can get into cars; groups can't leave the driveway. Single sims can go out but never return to the driveway when they get back (they stay off-screen).

I have Uni, NL, OFB & Pets (installed in that order).

Have you pulled all of your hacks and mods and tried it? Seems like there was some hack conflict that was causing this at one time.
