Sit target behavior changed?

Had something changed about sit target behavior? A multiseat plane of mine doesn't seem able to differentiate between its three seats anymore. Before this update, I could pilot, pick up a passenger, and a third person trying to sit would be ejected from a prim on the back. And I could eject the passenger from that seat.

Now I can pilot, but someone trying to be a passenger is ejected from the that eject extra prim. Even selecting the passenger seat directly does not help. Also, giving the eject command pops me out of the pilots seat now.

I haven't changed the scripts any, but today is the first ime since the update I tried to give someone a ride. Rather an annoying way to discover behavior changes.

I just tested this out on a two-seater by onother rather talented builder of airgraft, and it's showing new and unwanted sit behavior as well.

I'd like to be sure I didn't miss anything in the release notes and am not the only one experiencing this before I rain bug reports down on the Lindens.

Additional: Just tried something. Sit targets seemed to act as expected so long as the root prim didn't have a sit target.

Mkay. I was wrong a bit.

It seems that an av sitting on a child prim reports the av's key through llAvatarOnSitTarget to the other prims as well, or at least to the parent prim.

** Nope, to the next prim in the chain.

Has no one else noticed this behavior?
