+MV output hatches are no longer valid hatches for the Primitive Pump and need to be replaced with either a ULV`(new)` or LV hatch.

 ## Conveyor and Robot Arm Covers
 Conveyor Covers, when placed feeding into pipes, allow selecting their distribution mode, between Priority (default), Round Robin, and Round Robin with Restriction.
 
-Round Robin with Priority mode has been changed to Round Robin with Restriction mode. The previous Round Robin with Priority mode was unclear, and nonfunctional. 
+Round Robin with Priority mode has been changed to Round Robin with Restriction mode. The previous Round Robin with Priority mode was unclear, and nonfunctional.
 The new Round Robin wih Restriction mode attempts to evenly distribute items, as in Round Robin mode; however it attempts to *not* send any items down Restrictive Pipes unless there are no other valid destinations.
 
 Robot Arm covers, when placed on Pipe *exits*, can now appropriately limit item outputs using Keep Exact mode.
-However, a Robot Arm being used to transfer items *into* a pipe, still cannot use Keep Exact mode for transfer; it will not move items.
