The mortal enemy to the assassin order, a Haystack out of which one cannot get out. The one weakness they never saw coming, would be their doom.
To exploit this weakness in the game, complete the quest "Childhood Sweetheart" and then fast travel to Colchestre. There, from atop the spawn location, simply jump into the Haystack. You shall see, that is the last thing you'll do. I sure hope the TemplarOrder does not get a hold of this..

@phdzhivago What a prickly situation! Many thanks for the report. Not to worry, your secret is safe with us. We'll be in touch soon with updates on how best to remove yourself from all this hay, so please stay tuned!

@phdzhivago Thanks for waiting! Are you able to provide video footage showing this issue occurring? Once received, I'll be happy to send that over to our teams to be investigated further.

@ubiexcellent Hi, i encounter the same problem, of being stuck in a haystack. I am now in Jutunheim, on top of Serpent´s Tree, and if i jump in the haystack i get stuck. I can shoot arrows but i can`t get out. I have made a 1min and 20sec video, https://drive.google.com/file/d/15BPmUNTRQh7i5XO6Ijq6rgdPEnuvVLWk/view?usp=sharing: (https://drive.google.com/file/d/15BPmUNTRQh7i5XO6Ijq6rgdPEnuvVLWk/view?usp=sharing)

Hello @onpillsdude, welcome to Discussions.

Sorry to hear you got stuck in the Haystack in Colcestre, Essexe and thank you for the video provided.

In the meantime, our teams would like to use details from your progress on Assassin's Creed: Valhalla to make further research.
Please make sure that your latest save has been added to the Cloud (it will have a cloud icon next to it). This step will allow us to use your save files for investigations.

Please let us know once it's done.

@ubi-oxavo the latest save is in the Cloud. Thís is not the first time it happend.

I sometimes find Eivor doesn't want to get out of a haystack that quickly, can take up to ten seconds of rotating the movement and viewing sticks pressing jump. Is this different? Yes, probably is, I've not seen her stand up in a haystack like that.

@spirantcrayon22 you can shoot enemies while sitting in a haystack, in my case stuck, but i can still do it, just that i can`t get out. Not the first time in happend.

This is a common "feature" in this game... I've experienced this many times together with other "features", such as: Eivor can't use ladders (neither go up nor go down) when walking (I have it set to simply click left control on keyboard to toggle walking, not hold). My theory is that it's linked to this since when I click left control on keyboard to toggle jogging, Eivor magically recalls how to use ladder, leave haystacks, etc...
Not that I would comment on this but I've already reported this few months ago and it's not been fixed since that so I would not expect it to get fixed. Just a little irritating "feature", one of many...

@mr-operator you are right! the moment i changed from walking to running i can always get out of the Haystacks. @UbiExcellent @Ubi-Oxavo maybe you can do something about it?

@onpillsdude @MR-OPERATOR

ah, it's a "free running" thing maybe - always been in AC games, that, with its mix of being useful and irritating

Eivor isn't going to climb without use of one button or another, same with ladders and apparently haystacks - I get stuck for some seconds then pop out but had no noticed any pattern, I'll give it a look

@ubi-mushy ofc i was, i used what i learned here.
