After upgrading to OpenSim 0.5, something isn't quite right at my OpenSim island Ciuso. It seems the avatar thinks it should walk at an altitude of 20 meters, when in reality the terrain is at 21 meters. When the avatar moves, it seems to wade through the grass, and when not moving, it's looking distinctly uncomfortable.
Notice that when I move under the see, the terrain sinks to lower altitudes and the avatar seems to be content with that.
Next up.. investigation into terrain heights in OpenSim :-)
