Make sure that Plantera is dead. Also, the background walls of the Dungeon dictate which enemies spawn.

The Slab type walls spawn Snipers. A Lifeform Analyzer will also detect a Sniper.

I know this, but my world bugged out and the dungeon has no slab walls.

Install Cheat Sheet mod and give yourself one. Just try to not go too power hungry.
