Just a test to see if this is a coincidence or an actual fix
For those currently affected by Magnus going berserk by dropping millions of meteors for none of the reasons listed below.
(currently known trigger for Magnus anti-cheat system, server is lagging, someone inside the map is lagging, Magnus is frozen/desync/lagging)
A particular post in the bug reporting section http://maplestory.nexon.net/community#%2Fshowthread.php%3F1417822-All-sorts-of-problems-with-skills-and-Magnus where the person is affected by Magnus activating his anti-cheat system for no reasons, seem to have fix it by shutting down his computer. (the anti-cheat system might be scanning the memory hosting MapleStory for any corruption)
So here I am wondering if it a coincidence that if the anti-cheat system stopped activating if someone else with a similar problems with Magnus fully shut down their computer.
I personally never experience this problem as my computer is shut off every day, so I cannot test this myself.
(window 8 requires full system shut down, not the normal one)
