If someone loses a bag or any items or ore and someone find it they can put it in the lost and found box and the person that lost it can go and find it there
Usually someone might use a chest no one really looks at(like the one in the miner’s house). They might also teleport into rocks, set up a hook for their bag and dm whoever lost it. I feel like an in-game box for lost and found would be manipulated so people would just take what’s there whenever they got the chance. If the person is online, best bet is to just mail the lost items to them. If you don’t know who the items belong to, leave them where you found them, if the person doesn’t submit a lost and found post in the discord, just leave it.
