Healing now has commitment
The official 0.4.0.84 notes say medkits heal in small automatic cycles, consuming 50 medicine each cycle. The process can be stopped, but interruption can lose part of the medicine; excess healing is redistributed to other damaged body parts.
Practical use
Heal from cover instead of treating a medkit as an instant reset. Decide whether the position is secure enough to finish a cycle, then reassess your supplies before taking another fight.
