HELP: No join button on some of my friends on my list.

[Caloy]

I was on a campaign with some people on my friends list. We were on Alien Oasis II and my game froze just as we killed Anubis, and when I tried to join/follow them, there was no join button on Plasma Pyramid. I know I bought AO2 pack but can't join Plasma Pyramid. I'm a level 34 archer, is the stage level limited? Or is Plasma Pyramid another pack I should buy?

Have you played through all of ao2? Plasma Pyramid is the last map of ao2. You can't play it unless you played all the maps before it fully!

I believe Thedexeagle is right. You haven't unlocked Plasma Pyramid yet by finishing the level (or levels) before it. You can't join levels that you have not yet unlocked, even if you have purchased the map.

Also, you can't join someone who isn't anywhere. When you are not in a town or a map, then you are in limbo, so there is no join button.

When a friend is in a map you can't enter, there is still a join, but you get told that you can't join it if you try.
