Glad you found this. This one caused some really bad headaches when I was doing photos during a show. I already thought that SL was really bad this weekend, concerning meshes.
Strange yet how many photos I could do with rezzed meshes, when there was a that big bug in there.
I had quite some hard time, though. Lots of relogs and teleports, because meshes kept vanishing and never reappeared until a client restart.
So I am looking forwards to a much better experience during the next shows coming weekend.
