Mastery bug

hi mpgh member...as you know..there are last post around this week or last week i guess about mastery bug
Some 'ass' said when you raise up both mastery at the same time...there will occur some bug when you left room after its raise on same time without waiting end match...so i did try that way 2 time...
as u can see from pic below there i try with shotgun and sniper 1st but fail....my mastery rank up like normal to pro 3 and pro 4
the 2nd time its pistol and melee...but unfortunately its fail also...so i guess there are no such thing like mastery bug..
what i'm trying to said here..
1.please conductivity of the information you've heard is true
2.stop repost other post without agreement with thread starter
3.Please provide video and screenshot for any of your post when some bug/hack you do working perfectly..
