Thanks for the answer Tinkerer.
The sleeping animation I was talking about is the "stilldrunk" animation that plays when you have the SLEEPING status.
Now as for update on my custom status.
1. I found out that using an incapacitated type status override my animation with the "still" animation.
2. Still no idea why CharacterReceievedDamage would trigger on misses. Could you tell me where I can find the SLEEPING removal code?
