I think I just experienced a version of this bug.
Had a decorating gig at Dirk Dreamer's house, who was a Proper Celebrity. His house was the penthouse of an apartment building, and there was no way for my sim to get into that building. Couldn't take before photos on the penthouse level the game forced my camera to be at, and on the ground floor of building where my sim actually was forced to stand (outside in the open, on the ground) there was no "knock on door" action, and I am guessing the elevator up was somewhere in that building behind the door I couldn't knock on.
Was able to teleport the client to me (MCCC) to get details, was able to before photos of ground level building door >.< then decorate the penthouse area in build mode, and take after photos (once again of building door), but when sim tried to get client to return to lot the sim got the no access/pathing issue emote. So had to fail the gig and take the rep hit. Despite giving the guy the pink bowling alley he wanted so much.
Needs a fix.
