In your load order, I see the following problems:
- Hair pack.esm should be deactivated. You're using Project Beauty so you don't need it.
- the UPP esp should come before the FWE esp so that you'll get the changes to vanilla perks of FWE while still getting the added Perks from UPP.
- check the Dynamic Weather page on Nexus, there's a new file wich will add rain in the game. Install it, keep the Enhanced weather esm and get rid of the esps.
- You need a merged patch, Mez's Merged patch will fit the bill (check the FWE page on Nexus).
