I am running around Eldenwood throne hall and as there is just running, throwing in invisibility potions and trying to hide behind trees or dying is the only thing you can do I realized that despite the invisibility potion the guards really seem to know exactly where I am so they can throw their detection spell.
That is utter nonesense.
I also tried to run zick zack in order to make a sort of guessing where I am by extrapolating last visibile trajectory impossible but still they know where to throw the light.
Of course I know that the server always knows where I am.
But sorry, the guards should not be able to and I think how guards determine where to throw their light needs some adjusting.
