would it be possible to: Make Cactus Placable Worth $0.3 But not break when placed beside a block? This would let us us cacti for various reasons, but not allow auto farming, as thats how auto cacti farming works. Just an idea ;] I hope its possible, and the cacti price can be addjusted, but no point since it cant be made auto. And i know cacti was banned because it caused lag because of all the auto farming.
Unless someone made a plugin to disable cactus drop, he can't disable it. Weather was a plugin he added that stops it.
