Thank you for using the Forums to create a Bug Report.
After reviewing the logs, it appears that both 9 Refined Platinum and 11 Platinum Ore were transferred between your Car Trunk and your Characters Inventory as mentioned. However, it can be seen that you then sold it to Vendor Odo Roth at the Refinery. You continued to play on the server, disconnecting 20 minutes later. It is clear that your items did not simply go 'missing' but were sold by yourself, this report is therefore Invalid.
