Giving items to sleepers?

I have a problem when I try to give items to sleepers.
The sleepers do receive the items, but after that all sleepers appear as online players suddenly.
Players who want to connect get a message that they are already connected.
Even if I give items to only one sleeper, they all appear as online.
Does anyone have an idea what is going wrong?

 

Show your code.

 

I think:

Code:

foreach (var pl in BasePlayer.activePlayerList) { //activePlayerList - its only for online sleepers
if(pl.isSleeping()) {
player.inventory.GiveItem(ItemManager.CreateByItemID(-____ID_ITEM___, ___HOWMUCH_));    
}  
}

 

I tried various code.
The Sample from zhulenejsnek also causes the Problem.

 

Code:

        void Giveitem(string id, int itemid, int amount){
            foreach(BasePlayer player in BasePlayer.sleepingPlayerList)
                if(player.isSleeping() && player.UserIDString == id) player.inventory.GiveItem(ItemManager.CreateByID(itemid, amount));
        }
