as the world does progress, so does the piracy banditry and robery, pls do smth about inventing new locks, like ones made from 200 steel (hard lock) , which could be broken for eg, with a steel crowbar made from ( 200 steel, 70 rubber ) or a (complex lock) 500iron 200 steel and 60g nickel with a drill ( 20 diamonds 250steel 50wood etc ) made from resourses that are hard to find and are'nt generaly found in one place, because the ship with a lock is usless, because if you leave it for a day or two, 90% taht you will find it robbed...
or, solve this prob with time and the lock braking skill, like
simple lock (200 iron) - no skill limit
harder lock (200 steel) - novicely and higher
complex lock (500 iron 200 steel 60g nickel/ bronze) - efficiently or skillfuly
because if there is a civilized city, so it has to have some ways to protect its goods, because its not that hard to make a crowbar in now'a'days and BAM all the locks are open
and it leads for like, the more progress the village made, the more progress the pirates must make to rob it...
