I got to level 30 before completing The House Always Wins. I got a Lieutenant Ship Requisition Token and was able to get a free Tier 2 ship with it. But all the Tier 3 and above ships are showing either Dilithium or EC or Zen costs. Are the free versions of those higher level ships tied to missions too? Or did I disqualify myself by advancing levels too quickly? Or is it a bug? I couldn't for the life of me find any documentation of the intended progression on the wiki or from googling. Thank you!
