I know its in early alpha and i know there are some issues with it. I have been playing the game fine until now. When ever i try to join a server there ping appears to be in the red or yellow, and whenever i do try to join it kicks me out like a minute or two later saying signature time checked out. (or something like that) Is there anything i could do to fix this problem or will i just have to wait ? ): please help
