I am currently experiencing some technical difficulties. My weekly challenge (Deadeye) where you accumulate 70 headshots to acheive the challenge is not working. I started this morning off with 0/70 and have been stuck at 12/70 since I acheived the daily challenge (Deadeye). I have since killed 15-20 enemies by a headshot. I was wondering if this is a known issue? Also, under my "specializations" there are two other specializations (Wetwork and Operator) but both have locks on them. I saw something online about the 8 specializations and if I played online by November 20th, I would unlock said specializations. What am I doing wrong if anything? Thanks for your time and help!
