You will want to report this issue via an in-game petition, Muckbread, so it can be investigated and appropriate information can be forwarded on to our Quality Assurance team if there is an exploit at work here. The forums, I'm afraid, are not an appropriate place to report these kinds of issues.
I'm sure your guild would appreciate items and gold back as well, so to report losses or thefts, submitting a ticket is the best course of action.
