Seems to have a couple of bugs since the new patch

A post already exist for the TT turrets big nerf, so i won't talk about it but still, this is really anoying... I've play with with Kalista and against her, and it seems that when your bound with her it's bugging the attack and auto-attack, sometimes it also seem like i freezed, but maybe that was just lag i don't know, maybe some people seen it too.... I am also unable to buy any champs, sometimes the market just can't open and when it does and i click to buy a champs the loading screen appear and the transaction just won't finish...Am i the only one with this issue? Sorry for my english, hope it's clear enough...
