The Rare Request[From Sky to Earth: Blue Sky] is unable to complete in 3 days because one of limited item[Superior Salvage Rope] is required.

But Superior Salvage Rope is not available for some players till next week(which still has to wait 4 days longer to reset the limited salvage ropes at the Item Shop)(edit at 9/25)

As far as I know the request is acutally start at 9/24 instead of 9/25, plus with maintenance delay which means less than 2 days is the actual time left for players to run and complete.

And there's no other way to obtain Superior Salvage Rope in game, not from shop or auction, not from other requests or mail.

That means the whole series of these new Sep. Rare Requests story are blocked and players can not experience whats so after.

[Edit at 9/26]

Never mind, turns out the gift item is 3-days only, not the request. - -
