Gold disappeared

Was in Kingsmarch, had ~9k in town and 20k on my character. Sent a ship to sea and when I checked my inventory again I had ZERO gold. What! I wasn’t even touching my gold, only loading a shipment with wheat and ore. WT heck? Did this happen to anyone else? Any way to contact GGG and request my gold back? I know it is probably not much compared to what others have but nonetheless I did grind for it…feels bad to have to start from zero.
