Hi there!

Usually the roration of the events is good for about 3-5 weeks from the week they are currently available. Meaning they are flexible and can be adjusted ofc based on how the management want them to.

As I backread some event cycles the last cave key rebate tracks back to July 8, 2021. Next week is the 6th week and still it is nowhere to be found. This is actually kinda disappointing, even for me as I have almost 3k keys and are still idle for too long. Do not to worry tho, maybe next time the gap would only take 3 weeks, just keep on collecitng hehe

I think there are players who suggested refine rebate to land on the same week as 7days of welfare. Maybe they adjusted the events for such request. :)

One way to take it maybe, they are just responding back to "same old content" that most of the unsatisfied players are always ranting about. So just maybe they made a little unexpected twist. Don't take it seiously tho, just my two cents xD
