I have Skyrim Special Edition for the PS4. In the Companions story line, I am at the beginning of 'The Silver Hand'. Skjor is stuck under Whiterun, non moving. This stops me from continuing the Companions quest line. I have to meet him in the underforge but because of this glitch, I can't.
I also can not continue the main story. I was never able to complete 'The Horn of Jurgen Windcaller' because Wulfgar is supposed to give me the final word of unrelenting force but he decided to chill out on a mountain next to the Graybeards' mountain or whatever you'd like to call it. You can keep doing the main story until you get to 'The Throat of The World', where you have to talk to Arngeir about Alduin's Wall. But I cannot speak with him because of the part mentioned before in this paragraph, he tells me that Wulfgar will teach me the final word of Unrelenting Force. So now I can't beat either quest line.
(Yes I am using multiple mods on this play through. Keep in mind these are PS4 mods, here is the list in load order if this helps: 'Invincible Dogs Of Skyrim', 'Lampposts of Skyrim', 'Rich Merchants of Skyrim', 'Ring of Increased carry weight', 'God Gear PS4', 'Go Away Map Clouds'.
I have confirmed with other players that they are having some of these exact issues as well. I sent a report to Bethesda but I am hoping this forum will generate some talk on real fixes unlike "why don't you go back to a save before" because those don't work for many people and I don't have a save that far back nor do I want to lose everything I have done.
