PBEM replay issue

[Tankertony]

In one of my pbem games me and my opponnent have observed that part of the replay is missing. Effect of the action is seen after replay, but any action happening in LOS is truncated from the replay. Has anyone seen something like this before? Is there a chance that our game file got corrupt and we are doomed to this glitch and would need to restart the battle to fix it? Replays are important in my game play and I would not want to see this happenning throughout entire battle.

The issue was seen on EF with latest patch. Also I completed a game with this opponent recently without issues. Any suggestions?

It may be the effects of hidden shooters?

That is a good point. I am his opponent.
This is a very very rare event. I suppose I've had a 'corrupt' file twice in the last 18 years.
I play with a powerful HTPC system I built. Not one to have any other programs or resources running simultaneously.
Never a problem with this game. It happened to us both. On opposite sides! So definitely some Space Alien shit going on.
