I don't know if it's the right category to post that in, but right now, that is a huge problem.

It turns out that my game no longer allows my character to go to sleep. Instead, my game crashes. So, I can no longer join the Dark Brotherhood. Is there something wrong? If the problem are, according to you, caused by mods, I will post the mods that I have.

Thanks for helping!

I would like to see your mod list and your PC specs please
