Castle Thorn and the Mystery of the Disappearing Circle

DUTCH_REAPER · October 2023

It’s just a massive bummer when going for trifectas and then this bug which has been known for years strikes members of your team.

@ZOS_Kevin @ZOS_GinaBruno any update to this not being fixed yet?

baconaura · February 2024

@ZOS_GinaBruno @ZOS_Kevin Still experiencing this on xbox NA and PC NA. is there an ETA on this?
This makes getting the HM almost impossible, especially during this event where the mask style page is dropping....

This is easily reproducible, and hoping to atleast get an acknowledgement about this bug from you guys...

me when the: ran hm countless times with desync because i've learnt to just follow my buddies closely. gg zos

This has been a thing on Xbox NA for a very long time. When my dungeon group ran the perfecta, we got around the problem with the circles using the following approach. We'd clear the dungeon and get to the final boss, activating hard mode. Then one player would stay in the dungeon, while the others logged out, quit the game, and closed the game from the Xbox home menu. Then you go into your settings -> storage -> delete local save games. The Xbox will reset and then the players log back in. Once the players are back in the game, the person that is waiting in the dungeon does the same process: log out, quit game, delete local saved games, and re-log. Once everyone is back in the dungeon, commence with the fight.

This worked 100% of the time as we worked on completing the perfecta. It's an annoying pain but totally worth it to avoid the desynced circles issue.

Happy achievement hunting

3 years of this bug

Fix is needed.

Good thing castle thorn is today's pledge. Fix it ZOS

This is STILL happening, and the new patch added a fragment for one of the skill styles to Castle Thorn. It would be one thing if this dungeon was just abandoned, but to add new content to a dungeon that has been broken for years? That is insulting.

This is paid content. These dungeons are not free. People have to purchase this broken dungeon. And clearly you expect players to go back to it and replay it to access the new skill styles. How is that at all reasonable when *the* key mechanic of the fight is broken? @ZOS_Kevin @ZOS_GinaBruno

Anifaas · September 2024

Just experienced this. Really frustrating. This should have been fixed quite a while ago.

SilverBride · September 2024

This also happens if we get Lady Thorn as a boss in the Infinite Archive. It happened to me very recently and ended my run.

Vitgar · December 2024

The bug is still not fixed. @ZOS_Kevin @ZOS_GinaBruno

RealLoveBVB · December 2024

What surprises me is, that only the same players encounter this bug. In our dungeon group it's always the same player, who can't see the circle, while it's always working for the others. So I am wondering if that bug is really caused by zos and not a graphic setting or outdated graphics driver.

SilverBride · December 2024

When I've run the IA with a friend he always sees the circle but I often don't. I have seen it a couple of times so I don't think it's my PC, but maybe it is. I will be building a new system sometime next year so I'll see if that makes any difference.

I went through this fight with my stamDK character in January and didn't even know such a problem existed. Now I've found out about it with my magNB. The system is the same. Solo run.

Rastananana · December 2024

@ZOS_GinaBruno @ZOS_Kevin this bug is still there. We've been trying for the Guardian Preserved achievement, but it's literally impossible to do if even one group member gets this bug (which happens EVERY. SINGLE. INSTANCE.)

It's especially infuriating, as this is one of the only achievements I have left to complete and a bug that's been there for OVER THREE YEARS has still not been solved.

PLEASE have your team look at this again in the coming year when revising old content. This is getting ridiculous.

Me and my friends who I dungeon all have a PS5, I am the only one who gets the missing circle, and only in the dungeon, it never disappears in the archives

dehzr · December 2024

Was helping a new tank and new DPS run castle thorn unaware of this bug until last boss. I was standing on top of my team mates and taking 153k bat swarm while being in the circle on their screen. My screen of course the circle is frozen. Kinda hard going for achievements/playing the game when every other dungeon is plagued with bugs or server desync is so insane you either get kicked, die or makes the game entirely unplayable. Real bummer.

alcoraptor · February 15

This is still broken.
@ZOS_Kevin @ZOS_GinaBruno is this ever going to be fixed, or do we write castle thorn off at this point?

thepandalore · February 18

Can confirm this indeed is still broken. A potential fix might be to copy and adjust the Bahsei HM moving aoe; instead of taking up ~25% of the stage, it could take up ~80-90%

Evan4lmighty · April 4

As of less than an hour ago, this is still bugged. Tried all the typical answers of “turn off your addons,” “reloadui,” and “try a different character,” all with no success. Trying to stack on a group mate is just futile. It’s been over 4 years, either fix the bug or change/eliminate the mechanic.

Claire_Stella · April 5

So I also have always had this bug. 3 different computers.
I thought I was never going to get my achievements done in Castle Thorne. Then a friend told me to try the following.

Close your game down including the launcher
Delete this file from the ESO live folder
/Documents/Elder Scrolls Online/live/ShaderCache.cooked
When you start the game again it will make a new shaderCache.cooked file.

I now do this every time I need to go into Castle Thorne & it Works.
I now have every achievement done in there.

I think it bugs out when she dives at you in the circle as that is when the circle stops moving.

JDredd · April 7

I can confirm this is still broken. Also, when I was tanking this dungeon I was unable to use any skills on first dog boss. First I thought maybe its to prevent animal cruelty tbh. But, I can not even bash and what not. Also, the circle mentioned on this post was also broken. This was during a random normal dungeon. Thanks.
