Everything seems normal about the crab, we start at 10 ref, bump it up to 20, then a key, and I win each time.
Eon agrees to pay the key, and sends the trade invite, I accept, we both accept, and I wait for him to confirm.
Fast forward a while, I check my trades, and he had cancelled it. He had also already left the server.
