When you buy items in WebShop, I suggest you Dark Force MU players, to do the Simple things:
1. DC Your Account.
If You dont want to DC your account, then do this, its still works:
1. Be SURE that your vault its closed.
2. Be SURE that you have the right amount of space on your vault for the item that you want to buy.
When you are dealing with WEBSHOP:
1. Be SURE that you pressed the right Option, so you wont have to come forums and ask to admins to fix your Item.
2. Be SURE that its the item that you want to buy, because after you buy you cant change it.
Best Regards.
Good Luck.
