Joining friends Adventure

As the title said, I tried to join my friends adventure "Stealing from the rich" as we do the team adventures together, but this time the "adventure button" won't appear. We've tried reinviting, closing down the webbrowser, relogging etc.

It might have something to do with when I pressed accept invite I bugged out and when I came back it wasn't there (it wasn't before neither)
My friend "Allex" says he can't reinvite me because it says I am already attenting, please help!

Apologies if you have already done this...

Try to look in your quest log/'!' next to avatar. The adventure should be there... If you would like the little adventure box/button to appear on the screen, you need to have the adventure 'ticked' in the quest log.

If the adventure still does not show, please send a ticket to support

Yeah it worked, forgot to check there. Thank you good sir!
