That’s so strange, because for me it’s literally every character that I have with super jump, when I turn on double jump the icon in the corner immediately starts blinking. What’s even stranger, is that when my friend and I teamed up and he was also on a character with super jump, he had the same exact bug, except when I looked at both of our buffs in the team window they were both blinking...but they were blinking at different rates! But for both his characters and my characters, the icon in the corner is blinking as soon as we toggle on DJ.
