I invited a friend to adventure last night but for whatever reason he did not get online. After 8hrs I should have been able to invite someone else... but at least 10hrs later it hadn't released the invite.
I tried logging out, clearing cache, logging in, waiting.....
(In the end I just wasted the ls and completed the adventure so we could finish our guild quest.)
Could this be linked to the http://forum.thesettlersonline.com/t...-Not-Returning issue maybe? (My friend is "Active" though)
