I'm about to start the final quest, and the next step is to gather the companions before proceeding. It has to be at a specific camp, though, not just any fire. So I go to the required camp, summon them, watch a cutscene play out, and then the loading screen appears, and after a few seconds the game just freezes on the loading screen. Every time.
I've tried traveling to a different camp and walking to the required one. I've tried traveling to the required camp and sleeping, then summoning the companions. I've tried summoning them at other fires (they appear, but the cutscene doesn't trigger). I can always summon them at the required fire just fine, but no matter what I do, as soon as the cutscene ends and the loading screen appears, it's just a matter of time before the game freezes.
Please help. I'm so close to the end of the story, and (many) bugs aside, I have loved this game. I've finished every companion quest, won over every faction. I'm so, so close. But this is breaking the game for me and preventing me from finishing the main story.
