Hey, don't be affraid, this glitch is patched some days or weeks ago.
The glitch is the following:
People ask you to come to the wildy for a 'pk' vid or whatever, than they tell you you dont have to take valueable stuff in. They show you a large payment wich they would pay u after the ''vid''. Right before entering the wildy, they ask you to lend a rare untill logout, its just lending, so no problem.
But than within the wildy, the player offers you a armour set or sumting of 3pieces, than kills you, when ur almoast dead, the killer uses the lended item on you, wich will appear in your inventory, you die, and he takes ur rare.
This got patched, as you cant use items on eachotter no more to return lended items.
