Suggested fix (unconfirmed): Leave mobs at one hit so the bots finish them for you, or quickly despawn them to disrupt the bots' pathing. Alternatively, report the bots using your daily reports.

What players suggest
ive noticed most real people are respectable about where you grind. but the bots will do this thing where they will change direction when a mob spawns. like if i kill them all before it gets back over it will move on. if i leave one mob even little hp it will come over and try to ks then move forward into the same pattern around the map. also the names "ghdfsh" "sdfdf" "xcvc" are dead giveaways…
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.
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.
