Buffs with Sion bug

I do not have an image nor a video for this, but I can explain. This is not a huge bug but it should be fixed in my opinion. When you have a buff (Red, Blue or both) with Sion and you die, you still have the Blue or Red around you. However, you do not have the effects. It is not a big deal, but it is still something to fix. You have the impression you still have your buff, but in reality you don't. This happened to me in 2 different games and with 2 different computers.

N.B. The 2 different computers are both from Apple company.

I hope you guys can fix it.
