Last night during my gameplay I experienced a weird glitch. The bottom moodlets started expanding/collapsing and the sims stopped being clickable. I would click on a sim, it shows her face but the other sims moods, wants, needs and tasks. I recently started modding the sims so I am assuming it is a glitch with that? I looked up a YouTube video and found the MCCommander showing the issue but I still can't figure out what it is. I attached a screenshot of the page if the link doesn't work. If anyone can help me it would be greatly appreciated. Thank you!

I would go to the MCCC discord and go to their support channel with the log file/last exception and seek help there for it. They'd probably have more information and youre more likely to get a response there:

Good luck!
