[GAMEPLAY][BUG]Lee Sin perma shield Bug

This is another visual bug whne after Lee Sin uses his W/shield,it sticks to the shielded player til the end of the game. In this case it was to a Thresh. Az u can see in the screenshots it was first used on him in minute 4.and it lasted til the end of the game,even when after Thresh and Lee died,after Thresh responed he had his nice little buddy shield up. Altho it is nothing more but a visual bug,the enemy team might think Lee is oround and jut W to Thresh or they think its just the bug but Lee realy is oround,so its confuseing and unfair. I noticed it in few other games lets say 3/10 games that his shield sticks to an ally once used till the end of the game. To prove my statment az u can see on the minimap Lee Sin is on the other side of map while Thresh has the shield on him,an in one of the screenshots hes even dead but the shield is still there,sorry i didnt include screenshots from other games,but az it haponed a few times now this is from the last one. Here are the screenshots; http://prntscr.com/a47z7p http://prntscr.com/a47yv6 http://prntscr.com/a47yjm
