Since the update of today [22.09.2015] the chat seems to be a little malfuncitoning. Occasionaly I can’t type anything or doesn’t open on the first key press.
Also unrelated to this, but for awareness; Have a look at this please.
Cheers
Sidenote: The update seems to be quite nice! Congratulations on it! Will have to play a bit the next few days to see all the changes, but I like the menu layout change. Also I don’t know if you actually changed anything in that direction, but the last few MM matches were better than before the update!
