December 16 – Cancellation of Item Fusion Rounds 1 & 2 and Temporary Suspension of Reactor Service

We sincerely apologize for the inconvenience caused regarding the MapleStory Universe services.

Issues requiring immediate improvement have been identified within the Reactor system, specifically concerning reward calculation logic and bid snapshot functionalities.

Consequently, the results of Item Fusion Rounds 1 and 2 conducted today will be voided, and all submitted items will be returned to their original owners.

To ensure a stable service environment for Maplers, the Reactor service will be temporarily suspended until these issues are fully resolved.
* Reactor Temporary Suspension: December 16, 2025, from 10:30 (UTC+0) – Until Further Notice

The service will resume after a thorough root cause analysis and necessary improvements are completed. 
Further details regarding the rollback process and item returns will be provided in a follow-up notice.
