The reason that china put them seperated is because that the ninja that treasures provide are nothing compared to the jinchuuriki. Obviously people back then didn't know what treasure will be next, so they spend their seal scrolls on that merged treasure. Now it's like, meh, whatever, f2p and p2p alike aren't invest too much into it. Giving us the seperated treasure would have gotten you on our good side.

And how is the argument valid that the western servers should get the same kind of content when the updates in the different servers have been all over the place?

welp, another bug.

You can only claim the rewards of the daily reset ones and not the other rewards of survival and exam event. Basicly half of the rewards says they are "claimed" already even though the event just started....

Looks like someone forgot to reset the events from last time it was on...
