Hello! Today while ranking up I noticed that you are able to rank up without playing the required time. I only had 15 minutes play time but needed 30 minutes to rank up to Scavenger however it allowed me to rank up. I'm not sure if it's just this rank or others but it's worth going over and checking. View this screenshot for more information: It shows that 30 minutes is required for the Scavenger rank but as I said I was able to be promoted to that rank without that much play time. I hope this helps and is resolved. If you would like more information or a hand with anything feel free to leave a comment or contact me.
