If the game works on the new game folder, then you would probably want to keep it and begin moving your content and (other) mods in. You have nothing to lose but some time on also moving a save or two into the new folder and trying them out, or let's say a copy of the new folder so you don't have to do this all again if you end up in the same place as now. But as sittingbear says, my expectations for success on the older games that had indeed "seen" the KW mod are very low.

I wouldn't be overly concerned about deleted item replacements ordinarily. But among other things the mod tends to break the game's trait and dream managers once removed because of the irreversible way it alters those and those are essential for continued gameplay. We have no way to fix that. We are fortunate in that mods do not affect the game install (the Program files), only the user game folder and its saves, but I'm sure that's not much consolation when one really does have to start over.

Now where have I heard this before? Has a new hastily produced EP or patch been released by EA?

I'll preface this by saying that the system on which I am playing is not state of the art and never was more than mid-range when it was new seven years ago. I can't bring three just aged up sims into CAS in any kind of rapid succession and change everything about them (clothes in all categories, hair, CAS sliders, etc.) without expecting the game to run out of usable resources in the end and crash, get stuck, or Error 12 on me. What I can do is change one or two, or maybe stop at one and a half, save (as), quit, and reload then continue on. Triplets are tricky if they age up all in the same sim day around the same time, but I've learned to just be patient and tend to them more slowly rather than all at once.

That's not a fault of MC CAS, it's the game being its 32-bit charming self. Whether it's usable RAM (~3.7 GB is the absolute limit), video memory (vram) or something else difficult to nail down that it's running out of I can't determine, but there are barriers there preventing many of us from doing as we would like immediately in such circumstances.
