Round table

Has anyone encountered this issue?

So, the date is 137. I'm red. After the blue player's turn, it's still 137. My turn comes up, it's 141, I click "repeat turn," and then either the hero was dismissed, or something else happened; in short, my heroes disappear. I ask the opponent to load the AUTO save, and he does.

But when it's his turn, it becomes 142 for me.

Question: Has this happened to anyone else, and is there reason to believe this was a maphack? (in HotS)
