I want to start off by saying that if any of these have been addressed and fixed in previous threads, I apologize for bringing them up again and would appreciate any links to these fixes.
As I already saw has been posted and is being looked into, is the Mari Lwyd cloak glitch. It didn't seem to have a fix yet, but if anyone knows anything more, please let me know.
Next is that I have killed every Order of the Ancients member and pledged to every single region, yet I never got the last clue for The Father. I read somewhere that there was a mission to be given by Hathym, but I never received this.
After completing the Hamtunscire arc and speaking Randvi, I got the quest for Gunnar's marriage. I went through it and talked to everyone and got through the quest, but that's where things take a very bad turn. I looked at my quests as that's where my menu opened up, and it says I need to progress further in the main game to access the Yuletide event. I had already participated in the event and bought all the items, but it's now locked me out. I tried to run over to the event location, but I can not leave the wedding area as the camera is now stuck in that section, zooming out like when you get too close to the edge of the world. I am also unable to fast travel to any location or even another region. This was my breaking point, as throughout the course of my gameplay I had experienced countless and numerous times where my game would just crash out of nowhere. Either in a cutscene, getting hit by a spear off my horse, or simply running around.
I have the digital Ultimate Edition for Ps4 if that makes a difference.
Again, if any of these have been looked into and fixed, please feel free to let me know and drop links to the threads. I loved Valhalla, and constantly kept an open mind, but I'm reaching my limit.
