Untargetable Tristana - TFT

Hello. First I would like to complain that I was unable to save the game as League would immediately bring me back to the home page after my match and you cannot view TFT games in your match history to find the replays. I was just in a TFT (Teamfight Tactics) match and it was going pretty great. I had a completed winning comp (won the 3 previous games with it) and I was just a bout to claim my 4th victory tonight. Then, as my assassins jumped onto the enemy Tristana, I noticed that they did nothing about her and proceeded to stand still for around 3 seconds then attack someone else. The Tristana in question was Tier 3 with Guardian Angel and a Rapidfire Cannon by the time I noticed this bug. It was as if the game was treating her as in the guardian angel respawn zone, thus rendering her un-targetable. I thought it was a fluke at first, but then in the next round my Warwick ulted her and, Surprise! , he immediately floated away from her right after ulting. This was insanely unfair and I ended up in a close 3rd place as a result. Please fix Rito. [sg-ezreal]
