Do i have to start again and lose an achievement? The other challenges are locked because i could not finish this challenge. I took down all targets yet the challenge keep going on. Fyi, when i shoot the last one, the page went blank and it told me error happened and asked me to contact developer.
Can you PM me your user id and what network you are playing on? Looks like something messed up at an inopportune time. PM me that info and I will look into fixing this up.
