Impossible to disable Stealth once on the ground.

Doesn't being in Stealth mode represent actively hiding, and attempting to remain unseen? If passive stealth were a thing, involuntarily, you would at minimum always roll Hide when idle. It isn't just an invisibility button, after-all. The roleplay is that one is actively concealing their presence, not wearing a camouflage cape.

Yeah, that's what I was trying to express. If a character is hiding and gets knocked unconscious, they are no longer hiding. They are just lying on the floor. I guess you could argue they might blend in with the floor or something, but I don't see what business an unconscious character has rolling skills except the engine's limitations. It's okay if that can't be fixed. I guess a -100 hide debuff when unconscious could be applied to KOed characters or something. Or rogues can run with people who have AOE heals.
