Hi,
I have played several hours and noticed that there are every now and then gliches in gameplay. Some are graphical but the biggest problem is enemies behaviour. They do not always notice dead colleagues, there are many sudden freezes during battle. Also they don't seem to move around in camps and although difficulty setting is high they don't seem notice/hear things that happen near by.
How long players have to wait possible patch for this issue? Thanks for the comments. Excluding glitches the game seems to be 10/10.
P.S IGN.com also mentioned the bugginess of the game

The game has low quality graphics on the xbox one s, based on what i am reading on the Internet the xbox one version of the game runs on a resolution much lower than the 1080p that it should normally run, especially if one takes under consideration that i am playing the game on an xbox one s that has also the ability to upscale the graphics to 4k and i am playing it on a 4k hdr tv. The image of the game most of the times is blurry and the resolution is indeed at very low levels which is really unfair for the xbox one owners of the game. I am posting this hoping that if a large number of consumers communicate this problem to Ubisoft, that the company will be motivated to launch a patch that could better optimise the game for the xbox one. I played assasins creed odyssey more than a year ago on base ps4 and the game had significantly better graphics than valhalla on the xbox one. Its a huge game with an interesting story and very good combat system but the graphics on the xbox one are so mediocre that it takes away a lot of the fun, the xbox one, especially xbox one s can to much better than that, its just a matter of optimisation. I am hoping that this topic will reach the ears of those responsible and that the game will soon be improved for us xbox one owners, i am sure there are a lot of us...

I've been trying to get this issue reported for a week and a half now but all of my Twitter messages are ignored and live chat is constantly closed.

After finding Ceolbert for the War Weary quest, it says I have to follow him. He'll run out, get on a horse and then go until he reaches some sort of campfire place. Once he reaches this spot, he'll get off of his horse and just stand there. I've tried everything I can think of to get him to move but nothing works. I've loaded up about 5 previous save files, restarted the entire game and the entire console and it's the exact same. This was a problem on both the previous update and the current one. I've seen plenty of reports about him getting killed at a later point in the quest which glitches it out but nothing about the problem I'm having.

I've had to just stick Valhalla on the shelf because this issue has made the game unplayable.
