I'm not sure when exactly Auto-Health is applied, but the minimum health required for its application is at 50. I believe Vavoom does it at around 0 or 1. I guess as an addition, there needs to be the ability to turn auto-health off.

IIRC, Strife didn't disabled this in any way... but I'm not sure.

Check F1... it's the 3rd screen. F5 toggles Auto-Health On/Off (not that Vavoom needs to be binded to that, but there was a toggle for it in the game).

Fixed. I don't think we need to disable this for now.
