Sims 4 Stuck on Loading Screen (Mod or CC issue, or something else?)

@AnElBo The message just means that it can't access Deaderpools site to get more info (for whatever reasons).

Since it loads when you remove everything but MCCC, a mod/cc is at fault. Best thing you can do is remove MCCC as well and check what the regular LE from EA says if you can't access the MCCC one.

(use a backup of your save).
