there is a bug, example : i set a price of 500 per field protection, a pull down 1 block (-500$) and enter in drawing mode and to have a biger number of block available a pull down 2 another protection field block (-1000$) then i finish the cuboid selection my account was debited from -1500$ so its ok but when i broke my protection field the 3 blocs are droped but my account was only credited of 500$ (the plugin ignore the 2 others i put in drawing mode)...excuse my english ^^
