3.0.33 bugs:

If you talk to Stingtail as Sebille before using the tattoo needle you lose her quest conversation option. If you use the needle after and talk to him he just says "Not to worry I haven't slept..." and you lose the chance to confront him.

Roost's Rabbit Paw claims to give immunity to poisoned, bleeding and sleeping. It doesn't. It heals an elf (but not other races) and is not consumed when you eat it but stays for ever in your inventory to be reused.
