hello , I don’t know if the recent devblog 99.1 fixed this but there was an exploit with furnaces, altho its small, a furnace to be removed costs 50 wood , when you remove and place it again u get 100 wood as you do when u first craft it. witch means the player could gain 50 wood every time they remove then replace a furnace.
This is clearly a modded server, which means this is an exploit of the plugin, not the game. No one here can fix that, only the creator of the plugin can.
the server owner can as well by going into the Remove tool plug Json and editing the cost to remove to match the wood to 100.
