I just started having giant angled planes appear in world in Kama City. I thought it was a viewer problem, but it's happening on both a Linux machine running Firestorm and a Windows 7 machine running the LL viewer.
Current LL viewer, Windows 7 64-bit
Firestorm 5.1.3, Linux 64-bit
Is this a bug, or some kind of griefing? In Rhodenwald and other places in Kama City.
