Bug with Eternatus vmax, Collapsed Stadium, and other cards that modify bench spaces

When I am playing a match against Eternatus vmax or if I or my opponent plays collapsed stadium the game just freezes. For example if my opponent plays a crobat as a 6th bench space for Eternatus the game just freezes and even when the timer runs out the game does not end and I have no choice but to concede and as a result I lose ranking.
