Thanks Chris, I have contacted them. I think this could have been a ploy by the manager to maybe try to get some sort of benefit. I'm guessing he "might" have had a injured player who was then able to play.
I am not sure if it worked or not as maybe the player was not well as it was not counted as the next day? I think it only switches days once the server has been down.
Anyway, I am sure they will fix this issue.
