So me and my friend finally hit mirage, and he got off to go do some things. I quested slightly ahead, and made it to the quest past the one where you have to enter the Ghulture's Nest. However, now when I go back, I can't reenter the sigils. They're lit up, but there is no message box (the one that says press "x" to join and team up) and when I hit "x", nothing happens.
