That quite literally is what just happened to me, I wake up hoping to find new cheats, Ryujinx updates, and now none of them work. Stamina and others worked on 1.1.743, going back to that version for the time being.
Did you mean the Captain? Or actually the commander at the top of the building? Either way, this did not work when I loaded the code.
Edit: Okay it worked for some reason, I had to do two expeditions into places for it to work though.
