Lunatic Cultist won't spawn!
I destroyed all the cultists near the tablet but the lunatic cultist won't spawn. I have checked everywhere to see if there are any left (including down the hole). I have provided a screenshot of it to show what I mean...
I need help because I would like to be able to use this world for pillar destroying as I prepped it for use on the pillars. I even made an AFK Moon Lord area so I could focus on just the pillars.
Solution 1:
There used to be some problems in regards to the Lunatic Cultist spawning. I suppose they haven't been quite fixed. In general, to prevent any issues you should avoid altering the dungeon entrance. Specifically removing dungeon bricks. It messes with the boss and the cultists spawn point.
Rebuilding the entrance may solve the issue, however since you already killed the cultist you may have to wait 2 or 3 in-game days. If they still don't spawn, try 5-6 days. If there's still no luck I really wouldn't keep trying on that world.
