Inhibitor Turret Dealt 1397 Damage to me in first tick of damage

Character build background: I was playing Ezreal I believe I had a Tear , Sheen , Boots , and Dorans Ring . Summoner Spells were Flash and Heal . I had a few kills and a few deaths as well, my score was positive tho. I was using Debonair Ezreal skin.

Bug event that occurred: I believe I was at full hp, I had just about 1350 max hp at the time. One or Two team mates were attacking a turret with me. Enemy Trundle was there and I shot a Q at him. Trundle cast his pillar on me and I got knocked up right before my Q skill hit him. Q hit Trundle. Turret changed agro from minnion onto me. I died immediately with the only damage from the turret (1397 damage) and a status effect from Trundle.
