Is there host migration happening in any of those matches? That can mess up recording.
Normaly when theres a host migration there will be two seperate files for that game in theater. There was no migration in the last few game I had, the recording just stops.
Yes, checked it now. Nothing to do with host migration. Its like that in all the recent matches.
I've had this happen a few times; sadly it only seems to happen when I get really good game
