Hello,
Your picture isn't completely clear as to what is wrong. Are you just missing the interface to the right that shows names you can click? Are you completely incapable of interacting with other players? The screen looks fairly normal for first loading into the event. Can you further explain the problem?"
Thank you!

OK, I will look into this problem for you. In the meantime, the most likely issue is that it is on your end, since no one else has reported a similar problem. I notice that both you and the other person that reported the problem (your friend?) are from the same country/region. Are you possibly friends or related? Are you using the same internet connection? If so, that would make it even more likely that this is a connection issue. The best immediate fix would be to try using a VPN to play.
Also, do you have this problem in any other events?

EDIT: Also, are you capable of BEING attacked during the event?
EDIT: And what screen are you in when 7:40 server time hits?

Yes, as MocnaPest said, most people can resolve your issue by simply refreshing, which is why I think your issue is a bad connection. I haven't found any record of a persistent problem.

7:40 would, of course, be PM. That would be when Sage World Battlefield starts. 19:40 server time. The point at which you get pulled into Sage World Battlefield. Exactly what are you doing in game at this time?

As for the VPN, try a multitude of other regions except India and see which works best.
