Thanks DrRockzo! (wow that's not something I thought I would ever say xD)

Love your ships man

Yup, it is very strange behaviour, but I think I'll do the re-piping for the miner's sorter now anyways, just in case Keen find a fix

apparently hydrogen tanks can still stockpile through sorters. Keen themselves said they can't control it. So that's not a problem for the moment.

Yeah I see that this became a problem a couple of weeks ago, I will have to do some re-pipping, and also add a second sorter to the miner docks to allow Hydrogen miners to refuel

Got a problem with the Hercules hydrogen engines. They're not drawing hydrogen through the sorter and may need to be moved around to be in front of the sorter.
