Error 0x8000704c6 Ori and the Will of the Wisps

UPDATE: so I used the backup save option when loading a game. And chose a save which was 20 minutes before the issue happened, and hold and behild, the game loaded, so I did not waste all those hours.

Sorry to hear it. Please make sure that your PC has no pending updates. I also found a post from last year where someone had a similar issue. They updated the firmware in the router. You may want to check on that as well

I just got the same on Xbox, when loading Ori is floating on a grey screen, and then the game crashes. Gets me back to the Xbox home screen.

What happened just before, was I was running quicker than the screen could be displayed. When Ori reappeared on screen, it was stuck between walls, and the auto save kicked in. Since then grey screen when loading the save, and this is after 16 hours of game
play trying to complete it.

A bit frustrated, tried the last 2 backup saves. But still the same. Will try a third one later.

Same thing happened to me, but on Xbox. Whenever I start up my game it cuts to Ori floating in some sort of gray background, then crashes. I'm loading from the internal hard drive. I tried copying the save file, but the same thing keeps happening.

This is not the first bug I've experienced with Ori, but definitely the biggest.
