Game keeps crashing, items are dissappearing or turning black as a void.

Why are my items disappearing or turning pitch black?! The update happened while I was playing last night and the game wont stop glitching and crashing since. Its even affecting my gallery uploads as i thought i could place the lot i upoaded over the glitched lot to try to fix it but it did not work. I spent a whole day on this lot and Im beyond devastated, PLEASE FIX ASAP! Its mainly affecting items from my recently bought packs like werewolves, high school, moschino, even base game items. Especially build mode items! All my high school pack fencing disappeared as did some wallpaper leaving just blackness :c
