It worked for me, thanks, I also deleted all my temp files on computer btw.

Also I do not have festival working, PC, save on cloud

I played normaly ca. 3 hours ago done Reda daily missions, get opals etc. now after claming this new Amazon Prime set for Valhalla, my opals were reset. I had collected all opals from maps and now they appear again, I lost all my collected opals (ca.300) and also ones recived today from Reda, and Reda shop is now empty. Or maybe festival's end broke this as it was also when end of the festival message had appear. Now I have also error [0xb0000194 after going to Reda and trying intreract). Play on PC.

@m1au
Have the same error now.

Hi I was able to complete Into the Fog quest and defeated Puca. It happened just exactly after this fight then avenge quest appeared. I'm sorry but I now do not remember name of the player I should avenge (didn't note it) .
No when I'm thinking it started to happen something wrong during the Into the Fog quest. As after first encounter with Puca, after objecitive to survive it, next objective is to follow the Puca and it is in the wolf form. In this moment it glithed in the air but I left it as it was and run to the main fight arena. In this fight arena Puca appeared without a problem in werewolf form and I was able to defeat it without a problem. Quest was completed and then avenge mission appeared. Avenge mission pointed Puca to kill but it location was in the gorge where I was chasing it before. The rest is in my original post. I hope you understand this description. btw I also attach image of glitched Puca in the middle of quest and image of Puca glithed in avenge quest (second image). I'm sorry I do not have video from this.

This is interesting glitch/bug witch I encounter: So after done Into the Fog main qust has appeared to me mission to avenge killed user. So I took it and it occured that I should kill once again werewolf there. Werewolf was marked but it was version from before main fight, when we were chasing it in wolf form. So it was bugged as in this case it was version from previous cutscens. So it was trying to attack but didn't do any damage to me and I couldn't kill it to confirm revenge and I couldn't kill it to confirm revenge. Revenge mission totally glitched couldn't be completed. I could without problem run with this werwolf touch him etc.
