Bots can steal multiple medicae charges, they can even steal a fully charged station and will do so very eagerly if other players are healthy.
To solve this, I recommend enabling friendly fire
(Optional: FF would only work on bots)
And sometimes they ignore it completely (preferable tbh) and continue on with ~half hp…
I’ve also had them travel extremely far for healing in certain sections such as the sewer ascender holdout (where the medicae is situated underneath the holdout platform). And then get disabled
