This was very weird.
You encounter and follow Puca, then you have to survive a fight with it.
I did, and then it was standing there, back in wolf form. Marked red as enemy, but not attacking and not taking damage.
So following it as the quest wanted was impossible. Reloaded, same.
I still found the site, and killed all, including Puca.
After finishing I got an avenge quest. Blackwoodz of all people, a well known AC youtuber.
Found his corpse, searched for the perpetrator - and it was puca again. Alive, not fighting, not taking damage.
I reloaded before game got off track even further.
Anybody else had this?

When you encounter the puca, it's supposed to run away after a certain amount of damage.
In my game this does not happen.
After a little bit of fighting it becomes immune to damage and the fight never ends.

Tried earlier saves and it keeps happening.

I am now stuck and cant continue.

@nldraakje I had this too (and made a post about it here).
You can still manually search for the gathering and continue.

Encountered a fault on the in the fog section of the DLC i have encountered a link to the video i recorded showing the fault please skip to 13:24 in order to view the glitch

When fighting the puca, after doing about 1/4 - 1/3 of its hp in damage, I can no longer do damage to it and it keeps attacking instead of running away as it should do. It still damages me, of course, which means I just end up dying eventually.

First time I thought it might be a glitch in the type of damage being done, so I've attempted it a few more times fighting in different ways using different abilities, but the glitch remains.

@ubi-borealis Thank you for merging and introducing a "New:" tag to the mega thread!

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.

I've also got this problem, fighting the Púca, once it's stun bar is down/halfish health down, nothing progresses. Púca just keeps fighting, but doesn't take damage. I've reloaded multiple saves, but no dice on changing it.

I haven't encountered an avenge quest in the region of the Púca, I may have gotten one out in Tuam last night in the lead up to this quest, but none in this area.

Apparently, commenting about it and resetting my game one additional time fixed it for me, I have no answers as to why. 17th reload's the charm?

@ubi-borealis
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.

Hey there. Same issue for me. It almost looks like the puca visually glitches for a fraction of a second at the start of the battle.

I have not gotten an Avenge Quest during the quest line. Like the others have said- normal damage to Puca till about half HP. Then no more damage. The sound of my blows landing also doesn’t sound right- almost like I’m trying to kill something that can’t be. (Probably cause it’s not supposed to die- just trigger the next phase)

Multiple multiple reloads do not change the outcome.

Im running out of outposts and side quest things. Lol! Anyone else have a fix/ workaround?

Thanks! ᛟ

@paraflier Leave it standing and manually search for the gathering. It's nearby. Then you can continue the quest.

@kormac67 Do you mean not start the fight with the Puca and just head to the left? Is it possible to skip the battle and still move the quest along?

Once the battle starts, there is a boarder around the immediate area that prevents leaving.

@paraflier You have to fight the puca, until it stops fighting. Then it is supposed to run away and you follow. Instead it just stays there, invulnerable.
Then you have to find the gathering on your own to continue the quest.

@ubi-borealis thanks for the reply all. My issue is the fight with the Puca will trigger and I can deal damage to the enemy. However, once I get the Puca ‘s HP about half, I cannot inflict more damage. The Puca keeps fighting me. I cannot escape the battle due to the boarder around the area.

I can still land blows on the Puca but it doesn’t get any more damaged. The battle goes on forever. Or until I die.

No avenge quests, (I did notice that suggestion) have tried multiple reloads and save files. All the same issue.
