After last bigger update i started to experience really annoying bug when you trying to join friends match by clicking on join arrow and after few second you can see that these circles that suppose to move around each other stopping (in this case they has already stopped) and i can not do anything but press alt+ctrl+del and log out of windows session because anything else is not working neither alt+f4 which helped in other case. Task Manager is not even appearing after clicking on it. Then after that i need to run game client and game againg from beginning.
