Like we said, grandfathering in is an option especially for stuff you've got wrapped up in plots, so the suit and the tower can stay.

We mostly came up with this partly to shrink the city and also to come up with more challenges. Like when the palace was here Emma and I were basically able to get away with coming up with the library with all the info on the O.Z., and the ballroom, and Ambrose's old lab, and all this random magical tech stuff to sort of handwave fall back on. That wasn't a bad thing, we had fun with it, but it also made our lives ridiculously easy.

So we were thinking as mods that maybe taking that crutch away going forward will be beneficial, plus keep the size/scale of the city more manageable. Additionally it could allow for swapping out programmed possessions that aren't working as well for people, like I'm definitely ditching the hedge maze in favor of...I don't know, maybe Demilo's wagon.

tl;dr - you're fine for getting grandfathered and will be able to keep both, especially since it's been plot-beneficial for you.
