Slitherine

I have a situation where when looking at "opponent's" turn", on the turn indicator screen it shows that an opponent has sent a turn several hours previously, but there is nothing shown under "my turn" as being available. I have other mp games going on at the same time with no such issues.

This has occurred in my game with "Neccromancer." We are doing the Stalingrad scenario.

Any help would be appreciated. Thanks.
