I am also still having problems. Connection failures are keeping me from logging in and then kick me out in the middle of fights when I do manage to squeeze onto the servers. Between the server/connection problems when AvU began and the last 24 hrs of trying to get BACK in, I haven't been able to do more than a couple rounds. SOOoo frustrated...
To everybody in LL2, I'm so sorry I haven't been able to contribute more.
Just weighing in on the issue Alliances are experiencing where the main Avengers vs Ultron sub-chapter is closed after Round 8 is done. We initially designed it this way because when you reach the point target in Round 8, you’ve beaten Ultron. This wasn’t intended to promote inter-Alliance combat, but it has and that’s not fun. Thanks for the feedback about this. We’re looking at fixing this issue in the future, but won’t have a fix in time for Run 2.
After this run of Avengers vs Ultron finishes tonight at midnight, if you got locked out of progression rewards because your alliance finished the event early, please contact support from in-game. We're looking into ways to make it up to you.
