Where are the Royal mercian cript monsters?

I recently obtained the key for cript n1 in the mercian cript. When I try to go in, there is no monster to kill. The doors are closed and I can not go out of the cript. Also the tome that drops out when u kill the monster is not there. Did anyone has this problem before? Someone knows what can I do?

Never happened before, or at least it was never reported. I think if you reload your last sleep autosave it'll probably spawn correctly, sometimes phones glitch if during spawning the game gets minimized or somehow interrupted.
