My MAI presently has a caffeine buzz, from coffee that is from one of the mods I use (I think Finer Things).
She has a thought of Sick, -5.
Under Health/injuries, "Whole Body Caffeine (wired)"
Due to that, Consciousness is 115%, Movement is 120%.
It's kind of amusing, to say the least.
Edit:
Well then...
Of my two MAIs, I was checking them and saw that Mai_Beta has Caffeine (Jacked up), and the previous one, Mai_Alpha, now has Hangover (pounding)
So, yeah... they can get drunk and hungover...
Edit 2:
Bug report.
The 'knock out MAI if very low energy' thing can cause major damage to an MAI.
One of my MAI severely injured without warning. She was off in some 'dead end' corner of my colony (literally, game AI having bad pahtfinding involving building walls...), when I got a 'colonist needs rescue' alert. I found an MAI with major damage, nothing is around, on account of being 'walled in'. When I checked the health tab, I was a bit shocked.
Whole Body: Anesthetic. (understandable, considering the 'knock out' thing)
Right Arm: Crack
Left Leg: Gunshot
It would seem the 'knock out' thing is capable of crippling an MAI with severe damage.
If that other 'beaten to death' MAI reported before was in a recharge station set as a medical bed, during the day, she wouldn't recharge (sleep), and could run low on energy, and if already injured, taking multiple severe injuries to already badly damaged parts could explain the 'beaten to death' part.
