I did a search and didnt find this anywhere else, so I thought I'd share. ALL the sigils, all over the game are broken. When one person uses the X to jump on the sigil, other people have to back uip then move forward to jump on the sigil. This is only since the summer update. Previously, we could all be sitting on the sigil, hit the X button, and we'd all be on it.
I've noticed the same thing. The X to join requires moving away and back. It makes joining with a full party a pain, especially on the Ultra housing dungeons.
Yes! This has made me go into Exalted Duels with only ONE team member. My friends always have to go back then forward just for the sigil to work anymore. There was SEVERAL times where it glitched and I got out of the sigil because it was having the same problem and I was teleported to the duel anyway even though I moved off the sigil. I don't know what is wrong with it.
