Maybe unrelated but, I have a robust computer, but that FEB update (the one that nuked the mod scene) made my game's build menu take minutes to load which in turn also impacted saving and exiting the game. From seconds to minutes! I ended up finding 1 (out of the many thousands of CC I have) item in my Clutter decor menu that was failing to load after that update. I removed it and it fixed that issue. Could be something as dumb as that. But also could be any number of other mods of yours, not just CC, impacted by this latest release. These updates are incredibly unpredictable.I deleted that, and a few other mods and animations BE suggested and it still takes forever sometimes to load into the game. Has since the April update. Sometimes its 3 minutes sometimes after 15 it's still on the title page.
