He threatened to retire her a few years ago due to poor sales, but we suss'd out that it was a lil cheeky strat by him to drum up more sales. He's either doing it because he's lazy or he genuinely thinks removing variety will increase revenue, either way, this is the beginning of his end.
He'll either bring her back some time down the line and claim a "rework" to the model or due to an error with her mesh she wasn't able to be used until it was fixed, or he'll double down and eventually remove a few other women too. Has there been any other women removed or just Miriam? if it's just Miriam then he knows she's popular and he doesn't like it.
Just to add more insult to his injury and absolutely braindead of an excuse, when did you guys last see Zombie 2 in a set? or the Ghast for that matter? What about Loco?
EDIT: Or is he only counting the popularity of the women? I'll ask the same about the Dickgirls, but you know where this is going.
