I created a world using the drunk world seed (for fun), found the dead living tree, dug down (for the dungeon), defeated the dungeon guardian, defeated golem, then used a celestial sigil crafted in another world to try out the Moon Lord fight for fun. I was in Master mode and DEFINITELY wasn't prepared, so I died. I went to the dungeon to kill the Lunatic Cultist and summon the pillars to try again, but nothing was there. I killed the golem again, still nothing. I did this about 4 times before I figured if that was the problem it would have already corrected itself.
What should I try next?

Sounds like you haven't entered hardmode by killing the Wall of Flesh. That's usually the trigger for Lunatic Cultist, considering Golem is dead.
You may also need to kill the mechanical bosses and Plantera; Terraria's boss spawn logic is pretty rigid post-hardmode.
