Is something wrong with my computer?

Hackers have gained power over The Void? This does not bode well for MapleStory.

and this was the first thing i thought when i saw the picture, L> enuo

It's not a map crash directly
It's an animation hack, they can summon the animation for any skill in the game/things like nexon start screen/level up animation/floating "GM" wings above your head.
If they modify these packets, it created an animation the game cannot recognize, causing it to crash

they suppossedly can spam the stuff (like say, mech o evan summon) to lag you into DC too
