So I found two issues:
1. I was posting random stuff with the SOL Simstagram and I suddenly gained 80k followers from a post, although I was previously at around 100. Unfortunately, I don't know exactly which interaction caused this, I'm pretty sure it was one of the happy ones, but I'm not sure.
2. Whenever a sim is currently performing a social media interaction, then they are unable to access the social media part of their phone to put another interaction in the queue.
Thanks for making the mod, though, I love the reality it provides, and I hope you can fix these soon!
