everything is normal on the avatar. When joining some games, if the avatar contains some dynamic heads, all head accessories with be removed including hair.
In my case, when using cheap dynamic heads to join Zombie rush, such as Stevie Standard head, and other low price dynamic head, avatar still contains all accessories, but when using more expensive ones such as Err…, then all accessories with be gone.
Expected behavior
keeping all accessories on any games with any dynamic heads.
