when I modify the drop rate of an item in otherdrops, it will no longer be protected by city protection in precious stones.

EX: make sand drop at a 50% rate in otherdrops, now anyone can break sand inside a protected area.

Is there anyway around this or will I have to find a different plugin for protection :(

Other drops doesn't have an api, no way to do it form my end. Gonna have to find another plugin.
