No idea - it could be caused by either a client-side or server-side network drop? Or, alternatively, if your account has been logged in for 6 hours you will be logged out by the game.

Hey,
Sorry to hear this, very frustrating. It must have misclicked the ladder - while there's nothing I can do to combat misclicks, you may find they happen less often when the bot is allocated more resources and/or is running on a more responsive network.
I'm working on an error correction system which is still a way from completion, this will prevent this misclick from causing major disruptions when released
