I seem to recall that the last version I played (2.30) had an attack on your ship leading to the armoury unlocking and a quest. I think it was something with staying outside tenaris during the night that triggered it. I've tried a few times, but nothing seems to happen and the armoury remains locked. Could be bad RNG or a trigger that stopped working in newer versions. I think it was questline from 2.30 notes: Quest: The Bot Collective.
I did delete the old version folder entirely and played from day 1.
