Recently the public stone generator farm on smp6 in town was griefed. This is sad when even in town public utilities get taken advantaged of.Currently there is a flag called build, more specifically it has a sub-flag called destroy.Could the sub-flag "destroy" get broken down with it's own sub-flags. Stating something like this,/res set destroy stone true...................Which would only allow you to destroy stone and no other type of block.This is perhaps needed now, more than ever. If we are to allow for in town public stone generating farms to exist. Then we should be able to protect them from users who would take advantage of such trust.
