What happened was that King0fPapaya was upgrading his arm yesterday and after he finished, he put the arm back into his vault. There was no lag when put it in the vault. Today when he logged in, the arm wasn't in his vault and also not in his char or any other char in his account. I'm not sure if this is a bug or glitch, so I can't really explain what happened.
Just a note, this arm disappeared yesterday after the database rollback, so this is not to ask for an item back because of the rollback. Also it was already upgraded to 1k crit just before the rollback, but he's not asking it to be returned to that stat.
He just wants the arm back because he's already modified it before upgrading so that it will have perfect stats when he is finished upgrading it.
Here's the SS of the arm after yesterday's upgrading:
Att Bonus: 521
Max MP: 2350
MP Rec: 172
As you can see, it's still low stats but he just wants those stats back because if possible he doesn't want to spend hours again finding another arm with same dura/block and spend another few hours to calculate and modify the arm.
