What I suggest that barriers be added to the minions DiabledBlocks list in the config (provided we use the plugin I think we do). I also think that it would be cool if there was a certain type of block that they couldn't mine that could be pushed by pistons so that there can be an effective off switch for minion miner farms. Why Ive had multiple minions break barrier blocks recently and due to not being a vanilla survival item they don't drop anything. I believe that minions shouldnt be able to break barriers or anything that shouldn't drop. Positives Barriers wont be unknowingly destroyed by minions Negatives could cause players to think they have issues when really it's just a barrier in the way of a block in front. How Provided I've found the correct plugin, it should be on config.yml under the list heading DisabledBlocks.
