Pump does not take into account count of buckets in stack.
Sep 19th 2012 #3 Empty buckets now stackable (16 max). To test put into adjacent chest full stack of empty buckets. After one pump operation, you get stack with 16 buckets of water\lava.
Sep 19th 2012 #5 Well, that's interesting and useful. You can not to use tin for cells, just... bucket it.
