You haven't fixed since ages that bug where the HUD just goes off completely which makes the game frustrating and when I've left the game to join another one hoping that this time your game won't be broken. I can't play cos of the 15 minutes ban? This is unfriendly why should I get "punished" by your faulty game?
I have reported this issue with video footage towards the support to hopefully address it in future patches (only to have it back 2 patches later of course). Most times I could produce it was when I was in the menu for instance to change some of my controller settings. It is very annoying I know but Peter, there is at least an easy fix for you which is on the key F11. This toggles the hud and if it is gone it will appear after toggeling once again.
