Apparently, tritium will be available from Refinery economies. Explorers Anchorage has an Extraction economy. Please make an exception in this case (or change the economy to Refinery: it's supposed to be mostly a scientific research station anyhow, and with the arrival of Carriers, tritium refining will become its most important industry)
Might be worth checking the availability of Refinery economies in other remote stations too.
