Weird Bug with Lissandra being Invulnerable to Auto Attacks

Hi,

A weird thing happened in my ranked TFT game just now. Someone put PD, Morello's, and redemption (I think?) on his tier 3 lissandra. No matter what anyone did in the lobby, lissandra dodged the auto. In fact, she still got mana from being "auto'ed" and then was pretty much unkillable to teams that didn't use magic. You're first thought might be "well, she was just dodging a lot of crits" but I was playing 6 brawlers and Kaisa with crit items. And for 6-8 rounds (we were the final two) EVERY auto from EVERY champion lissandra dodged them.

Just to ensure no one thinks I'm salty, I still won the round because Chogath is op with void, but this would be extremely abusable if it was possible to recreate.

Thanks!
