As you can see here the space station can receive multiple rockets of other products such as the maintenance parts but it cannot ever receive more than one rocket carrying people at a time, could this possibly be fixed? because it limits the size of the space station even though you can upgrade more you are limited by the single rocket of people at a time stopping you from upgrading further.

see it will never go past this because the space station cannot get enough people because it never has more than 1 rocket coming with people but all the other products can have multiple rockets coming at a time
