Bug: All units are possible in PBEM after viewing a finished game

[Secret45]

Think I found a strange bug. I watched the final turn of a completed PBEM game. After that I picked another game from the list of my matches to continue my turn. However when loading this I could see all of my opponents units. Leaving and reloading this PBEM match didn't help. Solved it in the end by exiting Southern Storm and restarting the game.
