This needs to be fixed. As is, there is no way, whatsoever, to wake a heavy sleeper during the night. You can't draft/undraft them, you can't prioritize a task.

They could be starving, in extreme pain, and on fire and they will not wake up. You can't even have another pawn wake them up (see how quickly someone wakes up in real life if you cover their nose and mouth, its an ingrained physiological reaction.)

I would like the option to, somehow, get them to wake the fuc4 up when needed. There is no reason for them to be completly ignoring their physiological needs while asleep and sometimes they are needed.

Maybe add a nice, LOUD alarm clock or give another colonist the option of waking them up?
