TFT load up screen freezing game & disappearance of PYKE

i hope this is being looked into, but i've ran into this a few times now when my TFT game was on full screen settings and the game freezes. When this occurs I can't force close out of LOL due to it not allowing me to access the task manager tool due to it popping up behind the frozen screen. in order to resolve this issue i've had to shut down my computer every time and by that time i'm already behind in TFT.

The other issue i had the other day when trying out different tactics was with PYKE. I want to say it was around round 4 after the second player battle occurred i lost the battle, but my 2 start pyke with a bloodthirstier equipped disappeared and then reappear after the third player battler. I'll attempt to recreate this, but i doubt i'll be able to have this same set up.

One other suggestion i have is: could there be a way we are able to view recordings or of previous games or even download it so that we are able to watch how other players played against us and see what we messed up on?
