After getting captured in Junon, when you control Barret to lead him down to the press room - while walking down the stairs from the platform with the save point - rather than Barret zoning at the top and seeing Tifa walking up ahead, Tifa spawned at the top and walked the wrong way up the ramp and zoned back into the save room. From here I was in control of Tifa's model and, when running ahead to the press room, Barret never appears and so the scene does not progress.
I turned the translation off the first time it happened and tried again while saving in the room this time for the error to repeat again. Now when loading the save file, I start with Tifas model rather than Barrets, changing party formation does not help. Additionally, when turning the translation back on, the save point is no longer there (and it might not have been there on my first run, though I can't be sure) and in this scenario, the menu won't open.
