After growing up, face gone missing

Hi! Hope you guys are having fun with the new update!!

Unfortunately I was having lots and lots and lots of problem (and I'm sure this is probably the case for most of you) after the patch update+cats and dogs install and figured almost all of them out.

To list the ones that are fixed,

1.  CAS error (fixed with an newer version of more column mod)
2. UI missing (also fixed with new version of UI cheat extension)
3. Sims unable to adopt cat/dog, eat, or do anything (fixed by removing cc couches)

But two crucial issues have not been figured out, I assume that it's the mods and cc that are causing the issues but since I'm on mac, it is harder to use sims 4 studio to its fullest. Also I am not willing to remove all my 10 GB or go through every single item. I did try taking scrpit mod and some suspicious mods out but I couldn't figure it out. I was wondering if anyone could help me with these listed problems.

1. Saving or loading to different lots will randomly take forever which means never fully loading so I end up having to force quit and then reopen the game.
2. After growing up via candles, sim's face will be missing and only the teeth will remain. If I click on the sample (?I don't know what these are called but the ones that are the basic faces) the face will come back but it will get gone again with a new outfit.

I've force quit sims at least 13 times today and I'm really hoping to find an answer.
