Having attempted to get this NPC on two worlds now, I can reasonably assume there is more to unlocking her than just having free housing and right clicking her (this fails every single time).

In addition, I've tried with a wire block, a switch, etc. (found in the second world generated) and she won't be freed. Someone mind posting the actual method for getting this NPC or is my copy of Terraria horribly bugged?
