Slitherine

As I understand it in a MP game a player who does not meet the deadline will be idle after a while.
Is there some notification that a player is now idle?

I don't know how many turns you must miss before you go idle but it seems to be some. I suggest to lower this to 1.
If you miss the deadline there is no reason to keep the others waiting for you again.

I think its 3 turns.

Problem is the rules are set by the Slitherine server set ups, not by Empires. I also think this is the first game with the potential for significant numbers of players to be using that system so it may need a bit of thinking about how it copes - not sure about this.
