Why are my customers being paid by me?
This is the big reason we say NOT to go by the SL transaction log - what you're seeing there are actually REFUNDS, not outright payouts.
But everyone uses the SL transaction log!
CasperVend does NOT, and never did.
CasperVend has its own transaction ID's that are separate from SL. To PROPERLY track a CasperVend transaction, you need the CasperVend transaction ID - this is given to the customer in their local chat, regardless of whether the transaction has completed or not.
This CasperVend transaction ID NEVER shows up in the SL Transaction page.
