"Lockdown" Error Code 38 data gathering.

I think I understand the reasoning.

Basically:

You hold the window down.
Server Client won't crash the game from trying to load a corrupted item too many items since it will be stalled.
This stalled time gives enough time window for an item to expire if it has reached its expiration date.
If an item expires, the server will process the change instead of processing the corrputed item, and instead of going back to reload the corrupted item, just forgets about it completely instruct the client to update the item list, which will cause it to abandon loading the old list, and load the shorter one.
Player is able to log in.

If you do not have anything to expire, the glitch workaround will not work. Most people who have this error have had it for awhile. Long enough for something to usually expire. Hellmost people here are old players that I assume have pets with pet equips that are not perma.

Fixed to the best of my understanding.

Actually I'd guess that the longer they've been playing the same character as main, the more likely they are to have had the chance to get perma pet equips on it.
But yeah, thanks to Nexon's fondness for expiring titles, medals, scrolls, mounts, and everything else, most of us are likely to have something expire when we log in after a long time locked out.
