Hi,
Earlier in an MP game I was playing as medic but couldn't heal fellow players.
I went up to them, got the medic icon and also the option to heal in the action menu.
On selecting it, my character went through a heal animation and at the end of the process, the injured soldier's blood was removed and they looked ok. However, a second or so after this (the time period varied up to about 1.5 secs) the blood returned, they groaned in pain and showed injured again.
I tried several times with multiple wounded players with the same result...Might be worth mentioning that in offline games, I have healed AI characters successfully (not tried to heal AI in an MP game yet).
I'll try and repeat again later - but in the meantime, is there some gameplay reason why this should happen?
