Teamfight Tactics Bugs/Glitches (GAMEPLAY)

My first game of Teamfight Tactics:

1. I had characters randomly disappearing for a round of fighting, then reappearing after. This made me lose 3 rounds of the game.
2. (a) Character pathing bugs out often, characters will stop moving and attacking while standing still far away from the action.
3. (b) another bug of the pathing, despite having a clear path characters will choose to walk back and forth instead, thus losing you rounds.

All and all for my first match of TFT I was very displeased with the RNG of items (I had found 1 item by round 18) and the glitches/bugs that ended up losing me 1/6 of my rounds.
