Phaed, could you remove this from preciousstones.benefit.* node, or even better remove it entirely.

I dont know if they have figured it out on SacredLabrinth But a few of my players have have set /ps density to 100 and ran /visualize in a area with alot of p-stones. End result. read time out the whole server.

You can disable it from your players.

preciousstones.benefit.*: true
preciousstones.benefit.density: false
