I’m surprised I can’t seem to find anyone else posting about it. I’ve been experiencing weird animation/movement glitching that seems related to Halloween.
1. First time was after opening the chest at the end of Mad King Says. My character got locked into a weird twitchy run. Not sure if he was actually moving slower, or just appeared that way because of the animation. I kept hearing some sort of distressed like grunt which I think was coming from my character. No condition icon was showing, and it only cleared after I logged out and back in.
2. In the lobby of the Clocktower maybe two out of three times when respawning after a run I’d get something similar. Weird twitch walk, and when I jump, I’d fall slowly in a stuttery way. The fall is slow enough that the character does the scream sound they make when falling a long distance. I can also push jump in the middle of the fall animation to move back up (double jump in GW2!).
I don’t think it was just my machine, since occasionally I would see it happen to other players’ characters and watch them play with jumping while falling, too.
Dodging while twitching causes damage to the character, fires off one of the audio grunts as if taking damage, and clears the twitching.
