"Could not load combat replay"

I've run into this as well on a game I am hosting. Anyone with any ideas?

Looks like the issue was with one single empire's combat files, as the other combat replays in the combat file seemed to work just fine. This is only the first time this has occurred, but the battles were key to the survival of the empire, so if there is anyway to recover the replays for them, I'd like to know...
