Simply Zero

I have just discovered that a folder I had in my inventory that contained every piece of furniture, gardening, and house I owned has disappeared.....I am frantic at this point as this folder alone contained over 25000L worth of items and I can not submit a ticket for it as the ticket submission area does not have a catagory for it...Is there anyone out there that can please help me with this issue? I neeeeeeeed that folder!
