I opened my echo, went to the “Events” tab, looked at the “Challenges” for RotC. I scrolled over the rewards, and go to the one of the Head: Hotline Pandora, and exited . The preview for what my character would look like with the jabber head is still on the screen. It is there while zoomed in, changing weapons, reopen my echo, everything. Just sitting there taking up the right 1/3 of the screen. I tried it again, and now there is two of them overlapping . Only way to get rid of it is to save/quit.
