Shouldn't be a case of "half-loading" as you said, the game detects whether a mechanical boss has been defeated with one of three simple true/false flags (one for Twins, one for Destroyer, one for Skeletron Prime). If the game's announced that the Steampunker is going to move in, it would seem that the flag has been set. If you like, I could join your game via Steam and help you search for the Life Fruit? Otherwise, I could assist you in defeating Skeletron Prime again to make sure the game has correctly recorded the event. I have time now, if that works.
