Armor Plating (AP) provides a grid to vehicles without one so players can use armor plates to make them more resilient. Would you mind adding compatibility with it? According to AP's info page, you'd have to do this (after checking whether AP is active, of course):
Support for other mods vehicles to add compatibility, just add "vtk-armor-plating" to the vehicule equipment grid category :
table.insert(data.raw["equipment-grid"][entity.equipment_grid].equipment_categories, "vtk-armor-plating")
Thanks for your consideration! :-)
