Here are screenshots of my items on op pvp i have a lot more but i had to move most of it to my alts so if i get reset most of it is on my alts but this is what i have on my account right now.

I guess the Staff Managers do not have sufficient perms to spawn items, which is understandable because /gm 1 would be very OP for anyone other than an admin.
It might be because Administrators don't have the time to go in-game and refund everyone's lost items. I don't know the exact reason, I am sorry. May I close this? If you have any other concerns, feel free to private message me or if you have proof of a lost balance, feel free to post on the thread I linked you to.
