Transport cargo breakpoints

Try to alway hace cargo capacity big enough so you can carry 2 arts after you upgrade a red star scanner, or atleast be able to upgrade it after upgrading rs scanner, otherwise you will start to have hydro problems(going back to back for 1 art is rly annoying and hydro costly)

Note, this is the cheapest possibly method to achieve these capacities. Most likely, by the time you've reached the next red star level, your capacity will be other the requirements for one art, but under the requirements for two. Also note, the cost, is upgrade cost from the previous level, not the overall cost.
