Slitherine

I am playing a MP game with Lobsterboat, Kelly's Heroes (custom game). After opening his last turn to me I am getting the following screen.



Not sure what is going on. Guess we may need the turn restored from a previous? I have no idea what turn number is though.

You'll have to contact tech support (support[at]slitherine.co.uk) and ask them to restore the previous turn.
When doing so, please provide the username of the players, the name of the game and the scenario's name.
