Challenges not tracking

I found the issue after testing and testing hours after hours the bag you throw down as the support role so basically when you throw it down it takes a few ticks before it actually starts healing the player and obviously a lot of players like to run off straight away and never stand still long enough for it to activate the solution that helped me complete my 5000. Until this is fixed throw your support bag down on the body give it 2 seconds then revive when they get up the bag should start registering their health it worked perfect for me obviously took a long time as people ran off but the bag timer needs to be worked on to work quicker and maybe a bigger area for it to target the person hope this helps
