First of all, I am sorry that there is a problem.
There was a bug where animals in the wild suddenly died.
The animals in the New World and Plain(Non-pk) were urgently restored, but the rest of the world did not.
The Result
For NPCs only, New world & Plain(Non-PK) will have an hourly rollback.
The rest of the world will return to the August 2nd data for NPC only.
As a reflection of this, we will proceed the double experience event(it will apply both local and global.
you will earn twice experience until October 23th.
