Not Such a Huge Update?? Huge Consequences - Puzzling!

OK, so most of us know that yesterday's patch was BRUTAL on mods, and people said a BIG update was coming. But according to the patch notes, this patch seems kind of small, or maybe medium. I can't yet see HOW this patch affected, like, MOST mods from this list https://simsvip.com/2024/10/22/broken-updated-mods-life-death-ep-patch/

I know that these things don't always make sense, but I seem to recall that they used to, as far as I could tell!! (I took a 4-year break from TS4.)

So ... does anyone know why this update caused all this mess??? It really seems to me that it was a limited update NOT affecting this many systems. (For example, HOW did this update break loading screen mods?!) https://x.com/simplydeesims/status/1848816175448264731

It has me puzzling! ... Anyway, I thought it would be fun to discuss this. ... Hi!
