it's already known but i'm not sure we could call it a bug either. AI treats cell as potential harm to them.
Huh? You say, it is not a bug to waste antimatter on a cell on the AI's side, causing it to heal me 1 point a round?
Well, it is a very good way to discharge any antimatter the AI has. The cells take up space and heal me too.
As far as i see, the AI is also reluctant to devour cells, or mutate them (which would be the best solution).
