[GAMEPLAY] Red Buff Glitch ?

We had a team fight at level 1/2 due to a jungle invasion. Their jungler had red buff and I killed him and one other. As the AD carry, I returned to the lane with 2 kills, a BF sword and a red buff. Farming with it was strange, then it finally disappeared. However, I still had the effects of it ! My minions were burning, and last hitting was impossible and I wasn't even lagging. Later I finished my Infinity Edge and my Phantom Dancer and still couldn't last hit, the minions would die on me with no other allies or minions around to kill them. I also tried reconnecting to see if it would help but to no avail.. This burning minion glitch went on for 36 minutes even though I never got a single red buff after the first time.
