This is typically fixed once you change the area you’re currently in. But warpath will go down when I’m aiming up, if I stop channeling warpath I can then move up. This also seems to start mid-area, not when you first enter. All 3 times it has happened to me it has been going down when I aim up, so unsure if it is a bug with just this direction or not.
Wish I could give more info on the root cause, but I really haven’t noticed anything significant before it has started happening each time.
For a little more info, it has not affected the whole area each time, just seems like once I get above a certain “latitude”, warpath will always start going down when I’m aiming up.
Adding info, since I’ve started to track when and where it happens, it has always occurred in the Shrouded Plateau. I don’t know if this is the only place it occurs for sure, but this place definitely has a high likelihood of the bug happening.
For me its not so much going the opposite direction as where I point. Instead after a while it just insists on going in a specific direction no matter where I move my mouse. One day it will always go left. Another day it will always go up. Etc. Resets when I exit and re-enter the game but then it just comes back again. Makes that character unplayable.
