The beta grid has been 1.16.0(1) fixing all the bugs that Linden Lab says they know to exist with sculptable prims - although existing sculpt textures will provide inverted displacement (your inny bits will be outed, and your outy bits will be innards). To fix that, flip your texture horizontally.This version also introduces a new communication function: llRegionSay() which will chat to every listener in the region, but cannot use channel 0 (open chat).
We guess (but do not know) that this release is being aimed for 23 May. Either way you should check it out. Grab it from the usual place or see the release notes here.
