one thing i have to mention for another fact video you can use later, is that when you heal a idle teammate in the saferoom while they are idle and you close the door to skip the heal process, the person won't get healed because at the same time the door closes and you're healing the idle teammate, they also spawn in game and get out of their idle state, so basically even as healing applied, they won't get any health and you lose your medkit as well when next chapter loads up, the idle player isn't heald and you don't have your medkit too
