Why Is My Character Delete in Maplestory, Why Is That and How to Fix… (Workarounds)
Short answer
Suggested fix (unconfirmed): Check that you are logged into the correct server world and Nexon account where you created the character. If the character is genuinely missing and was recently active, submit a ticket to MapleStory customer support.
The problem
Why is my character delete in maplestory, why is that and how to fix this problem, is it because of maintenance?
Suggested fix (unconfirmed): Wait a few months for the player traffic to die down, or group with your fiancée to out-damage the competition. If you still struggle, return to hunt the boss next year when low-level areas are less crowded.
Suggested fix (unconfirmed): Verify your game files instead of reinstalling. This error simply means you haven't received the latest update through Steam yet.
