Riot dealing with bugs and glitches .
Riot fixes exploitable bugs so much faster than bugs that can't be exploited
Examples : there was many bugs such as you can't use your Q as
for the whole game or can't use Q or R as
or you lose 1 of your passives as 
and there was a bug where
could damage her own teammates .
Let's see how long did they take to fix those bugs
Bug took them couple of days
took them 2 weeks
took them 3 months
so they deal with bugs like
"Hey boss there is a bug " " is it exploitable ? " " No " " we will deal with it later"
"Hey boss there is a bug " " is it exploitable ? " " Yes " " Fix it immediately !!"
:P
What i say that they should deal with both bugs the same way because both may cost you a game
