I noticed that sometimes when I walk though a door (currently in the Ruins of Welryn) my pj runs slowly like trapped in a spider web. There are spiders but that’s not the cause lol
It’s random, like if I pass through the same door sometimes happens and sometimes not.
To me it feels that if you click on the other side of the door your character paths through the door & everything works. But if you’re holding down LMB & walking throug the door that’s when the pathing goes pear-shaped (perhaps the game goes nuts on trying to calculate a path through the door as you’re constantly asking it to redo the calculations).
