I couldn't find any thread already reporting this issues so I'll just do it myself.
I am repeatedly encountering a bug when Eivor tries to enter tights spots like crevices in caves or stealth entrances to military camps. Occasionally Eivor becomes stuck in the middle of moving causing both the screen and character to rapidly shake for about one minute before forcibly desynchronizing. Unfortunately I cannot get my computer to take a video, so the best I can get is a picture. The one shows the most recent glitch of this nature I have encountered where Eivor became stuck jumping the fence into a military base.
