I don’t care Too much, but just a heads up that if you have a downed character and keep tapping on the big center button that prompts to use a medpack (and then changes into fight), it will continue to use medpacks, even after healing your characters. I just used 5 medpacks to heal 3 people 
I’ve done this by accident as well. I was expecting it to switch to the next Downed character…
