Social Events Help

Is anyone else having issues where whenever they start a social event, the sims 4 gets buggy? For example, whenever I choose guests for my events, that's when it starts making most of the townies invisible and I have a party full of invisible townies. The only visible ones are my player sims. I also cannot change my sims outfits when this happens. Also another bug I found was I cannot save. It gets stuck on save and forces me to have to close my game and restart it. Another one is if I choose to have the social event somewhere other than my home, it just loads and loads also forcing me to have to close my game and reopen it. I am not sure if this is happening from the most recent update, but I did delete a mod I was using in the middle of my save file because I got tired of it. It seems like it might of started once I deleted that mod. it was the Simzlink mod by lot51. I am also unsure if it has nothing to do with the mod but is a bug from the recent update we just got. I never tried to start a social event after the update on my new save file so I am not sure if it's that causing it or something else. Is anyone else having this issue? I will also see if I can do events successfully omegle xender on another save file. But in the mean time, I would like help with this current one.
