There should be a cmb file, containg the replays of all the battles having happened in the turn (or all the battles you were involved in at any rate, but I think the file would include *all* the battles, including the ones between the AIs).

I do not have any .cmb file in my temporary repertory. Perhaps you could try clearing up that directory? (A backup would be in good order before that, as usual) Or perhaps you could try deleting the .cmb file in the savegames repertory, if the file in question is corrupted. Or you could try to rerun the turn, in case it is not a recurrent glitch.
