Event freezing issues

UPDATE

So I've closed out the game and reopened it several times since I last posted. The only way for me to access the Willow Creek library for the event was to take out my mods. I don't play with many mods, and I'm diligent about keeping my mode up to date. So I'm 100 percent sure these mods were not old or out outdated. In fact, I had pulled out my whole mods folder a couple days ago with the impending update. And since the update, I've only put back in updated ones that were confirmed as compatible with the most recent patch on the 3rd. What could be causing the whole of the Willow Creek library neighborhood to freeze on me if my mods are up to date?

I had a similar problem where my game would freeze at 12.03am. The mod causing this was the updated mccc. I took it out and replayed the game until I got past 12.03, saved the game quit the game and reinstalled mccc. The game has been ok since then.

Hmmm, I play with MCCC too. I wonder if that mod could be the problem. I have a suspicion that the event will have me go back to the library to pick up the key my sim found at some point. I'll try you solution and see if it works. 

Any idea why that mod in particular could be causing freezing issues?

Demigod083091​ I'm pretty sure it is a clash with the event. So far since I restarted my game I have had no further problems. Will have to see what happens on the second week of the event.

Demigod083091​ I strongly recommend only doing Events in a mod-free new save.

It might be a clash with the event, but I'm not fully sure. Only because that whole neighborhood has frozen for me before in other saves where I'm not involved in events.
