I believe the (self inflicted) issue I am having, is that I wanted a world basically used for building. I created it with no crimson/corruption, etc, in hardmode, so I wouldn't get the strips. I think this is the source of my issue, with no orbs/hearts to smash, NPC's never show up. I tried to force them in via CheatSheet, but the Mutant and Abonmination still aren't quite right. Mutant is fine for the most part, although I can't set his house, or anything. The Abomination has an empty store, regardless of what invasions I have cleared. Anyone have any other ideas on how I might get around this?
