I would like to ask for support.
In fact it is currently given to cheat in MP games.
After a turn it is possible to lead the game to a crash. All that has to be done to get n- new chances to replay your last turn is, to write more characters in the chat field in the "end turn screen" than the textfield could show. After doing so, the game will crash instantly. This failure for 100% reproduceable. So it seems to be a bug.
At the slitherine forum this bug is known (I can't link this. =( ) but its been a while now and no further response from the devs.
I think thats this is not a satisfying situation and should be solved.
Perhaps here at the matrix forum help will come a little bit "faster".

Thanks in advance!
