Herbalism, and mining

This sounds like pooling. On official, there were "pools" of each type of item in each area. Only so many could spawn at one time. When one was picked/mined, another instantly spawned elsewhere. This works well on populated servers. Not so much on solo servers.

Marking this as completed as likely was fixed with rainers new pooling system for this stuff. Please make a new bug if this is still happening.
