[Maintenance Complete] Maintenance was completed on Wednesday, June 3 2026 at 7:30 PM PT. Thank you for your patience.

____

[Updated 6/3 at 6:58 PM PT] Maintenance has been extended by 30 minutes, and anticipate the maintenance to conclude around 7:30 PM PT.

Hello Creators, 

We will be performing a maintenance on Wednesday, June 3 at 14:30 PT that will last approximately 4 hours and 30 minutes. 

With this update, the Global Creator Challenge submission will be available. In addition, a DataStorage usage limit, criteria for deleting past revisions, and a Player Ban menu will be added.

The “Player Ban” is a player sanction feature that requires direct implementation in Creator's World, provided by the platform. Based on Nexon account ID, sanction records registered in the World are automatically transferred to enable efficient player management.

* When a player with remaining sanctions deletes their MapleStory Worlds account and rejoins, the platform identifies the player's previous sanction history and automatically transfers sanction status. 

You can find the details of the maintenance below. Please note that the website, PC and mobile apps will be unavailable during the maintenance period.
