I've just unlocked the Corrosion Resistant Cargo Rack from a tech broker but even after this I can't find the item in the outfitting menu. I've tried going to several stations where human tech brokers are available but none of them sell the corrosion resistant variant. If I understand correctly I should be looking for the 4E version (16t) but everywhere I go they just sell the standard version. Am I doing something wrong or is there nothing to indicate that a given cargo rack is indeed corrosion resistant? It cost a lot of materials and commodities to unlock so I would hate not being able to actually outfit this to my ship. Thanks for any help in advance, Commanders.
