Game leaving / rejoining

I want to suggest the option to offer players a clear way to return to battle after leaving. I just had to leave game because of a bug where all hud elements dissapeared, only the 3d stuff remained on screen, no cursor, no modules, nothing. Then it was impossible to rejoin. IF that is NOT a bug, but a shortcut for screenshots, PLEASE ADD IT TO THE DAMN KEY BINDINGS so i know what the hell happened. It screws the game over just like that…

Someone tell me the shortcut if it is so, it’s the 2nd / 3rd time happening…
