"A reverse version of the conveyor corner piece that points in another direction. Reverse Corner is love, Reverse Corner is life."
The Reverse Corner is like the Conveyor Corner, but directs ores in the opposite direction of the Conveyor Corner. While it takes more space than a Corner made from Basic Conveyors, it is simpler to build and ores will not get stuck when moving to the part on which the ore will turn to another direction.
This will possibly be retired/removed from the game soon.
