did they make it where teens can't die ?

In addition to repairing your game and removing mods, delete your localthumbecache file. This file, for some reason, can glitch things when any changes are made to the game. I've gotten into the habit of deleting it every single time I patch, install a new pack, or add or remove any mods/cc. I also delete the files in my cache folder regularly to reduce bloating.

But it definitely sounds like a glitch in your game. Sometimes even a piece of cc can disrupt normal game flow. That's why it's important to test your game without any mods or cc first, to see if that corrects the problem.

Good luck, and I hope you find the issue.
