I had same problems during this summer. Couple of times even whole scenario was changed with other scenario, which I played same time with other opponent...

Couple of times it happened, that it looked like that my turn was posted well, but then it came out that whole turn was not saved properly and my opponent saw that I did not move my troops one turn long even I moved and believed that everything went well... Sad, if good game is not functioning properly, because of lacking server space or other problems with servers... But would some one answer, why this kind of problems are still existing...?
