In my game, little ED-E lost all of his health and now he has 0/0 HP when checking the companion wheel.
If he gets hit during combat, even the slightest damage will make him explode much like an automated turret,
vaporizing instantly and leaving nothing behind. There's no pop-up notice that ED-E is gone either.

If he survives through a combat, he will not automatically heal to full health anymore
and applying stimpaks manually doesn't work.

Has anyone else had this happen before and if yes, is there some solution?
