Yes what CPT Kwok said. You can add items to the end of the VehicleSizes.txt too. Although in the process of testing my Mod I have managed to add and even remove 1 ship size that was in the lower half. There weren’t any ill effects; however, I did not get to test this for more than two more turns before having to start over from a major change in the components. In other words just looking at the selection of ship sizes everything seemed fine but I never had the chance to build a ship from the list that was below the deleted entry. Was that confusing?
