Description of Bug: Pickpocketing gives no feedback when used on a sleeping heavy sleeper character.
Reproduction Steps:

1.  Have a character with the heavy sleeper trait fall asleep.
2.  Attempt to pickpocket the individual.
3.  Receive no feedback about whether the attempt failed or succeeded.
4.  Receive no items from pickpocketing despite multiple attempts.
5.  Mind is still used despite this.

Notes:

Hostile intent looting still works on a heavy sleeper, but I did not want to completely loot the individual who was asleep.

(Fixing update)

This seems to apply with any sleeping character, not just heavy sleepers.
