Previously it was the wrist/forearm that was being…deflated, and that was for all female Norn and only during /dance or throwing animations.
Your screenshot seems to show you as being in a combat stance and it appears that it is now affecting the upper right arm. I’ve tried to reproduce the issue with my female Norn, but I could not.
What gloves are you wearing?
What rifle is that you are wielding?
Perhaps it is one of those items specifically that is causing the issue now. If you’d like to include all other gear you have equipped, including a back item, that’d probably be really helpful.
This only happens when you are wielding a rifle, having it out and leaving her idle. She will lift it up for a few second and look from side to side. When she takes the rifle down again the arm deflates and inflates again.
Tried all sorts of armour, and rifles and the result is the same. Even tried looking at Sylvari and Human but the glitch is not there, only the Norn.
This is not your end it is definitely something that came after a patch or something.
My Female Norns arm does the exact same thing, and it’s not only with dancing, the arm also twists when you do the kick dirt into a hole animation, even the idle animation with a rifle makes the arm become distorted.
