Slavsan Deluxe

Hello everyone. A friend of mine sent me a gift and I received a message on the top right corner that said something like "You have received a gift from *name*" and such. I clicked OK. Then when I tried to find it in my inventory I couldn't and also my friend received a notification that said I deleted the gift yet I didn't. It happened twice. It said I deleted it twice. I didn't even get to see it in my inventory at all. Please tell me why it would be. Thanks in advance.
