Latest update is broken (24th July)

This latest update (24th July)  is completely broken. My sims have the best conversations and are best friends, then suddenly they start to get mean to each other for no reason?? They don't even have traits that could cause this.

And also the loading screen takes forever to load.

Anddd when my sims are in conversation the relationship bar above is looking weird and broken.

Please fix these bugs as soon as possible please EA  :)
