Ashe Hawkshot bug (permanent eyes above target on client side)

I was playing thresh vs ashe and zyra, and the Hawkshot spell from ashe is supposed to reveal you for a short amount of time, displaying eyes above your character. At some point I got revealed and the eyes were displayed from that moment until the end of the game (even though the ennemies did not have vision). It is maybe the 3rd time I see this bug, but I don't remember from which champions it occured the other times.
