The RM entry for the Soyo shows a picture of the Medium Cooler. However, when my crew IDs a ship as a Soya, the ship appears to be a Medium Heavy Load Freighter (I think). The tonnage awarded is appropriately in the 9100 ton range, whereas the Cooler is more like 3,000 or so. Sinking the Soyo gives the proper displacement credit - I think it only a picture issue in the RM. But it does confuse my crew.
This is small thing in the greater scheme of things.
