Balance has not been reverted to its pre-SL3B state. Autoreturn is turned on for the whole sim and there is a huge spike of land at the east border. Also, the "starting gate" thing with the number pillars and the bike track are missing.
Autoreturn is on in Fame, Fortuna, Bethel, and Georgean. It shouldn't be: this is a sandbox sim so it gets wiped twice a day anyway, and having it even as high as an hour is troublesome for people who are working long hours on vehicles. It was never on before, or if it was, it a lot higher than an hour. (And with the current "anything you rez is instantly returned over autoreturn land" bug, it's even worse.)
I don't know about Brilliant as it is being rented at the moment, but I hope it is restored to its pre-SL3B state when the art show is done.
Edit: Sorry for asking twice.
