if you always get 1 item within those hours then how come you got 0 items? perhaps you've hit your item cap for the week. if not then the reason behind your problem is likely because steam is at its peak operating hours. Try idle in exactly 12 hours time or when steam goes under 3 million active users.FF|Skyrider posted:
If that doesn't work then yeah it's random chance being super random. You can't rely on a random system 100% of the time. So keep idling. and use an online backpack checker such as tf2b.com incase you're checking your accounts in game.
