Maplestory Mutiny?

Localization is not that easy. It takes ~4+ months for a reason. Especially with the mess that is GMS' files.

Well, only for maple story (talking about nexon games I played mabinogi, dragon nest sea and GMS), for example the last chapter of mabinogi was released in Korea only 7 days before North america and the alchemist job was released like 2 and half months before in korea.

So, maybe it's because GMS team is a mess and they can't do it fast enough.

Edit: Or they don't want to break the schedule of "major patches" for example: Summer update in KMS-> Winter Update for Global. I f they only had 2 months difference they would need some good exclusive patches or events for the Holidays and summer.
