Kingsmarch Shipping mistake

Hi,

I know this was absolutely my own fault but I just made a huge mistake with one of my ships.
I went to kingsmarch just to check how much value of smelted bars I had fixed, but I ended up misclicking and sending the ship worth 13 mio in just bars, I panicked and hoped that by abandoning the shipment I would get some of the bars back but then realised I lost everything without getting any value for it.

I had slowly farmed this over the last week and was very much looking forward to sending my first 50 mio shipment :(

Is there anything that can be done or was this just a very costly mistake?

I'm afraid that proverbial ship has sailed, much like the literal one. No way to get back your bars or your rewards :S
