[GAMEPLAY] Trynda is killable by the chilling smite while in ult

it happened alot of time while the jungler ganking me at top i use ult to eaither escape or to complete a fight if the jungler used the chilling smite on me i die,, even while the ult is still on

i usually notice that specially when the jungler is fidle

it happened with other too , ww as example but that was in the patch 4.1

i heard that it was a known bug but even in the latest patch it still not fixed

thank you
