As title, Any Cargo that has been collected will remain invisible underneath its Cargo Space block and other Transparent blocks.
1) Astronaut mode, showing cargo, as the Cargo Blocks become invisible
{F4523}
2) The view seen from Build Mode, cargo no longer/patchy visibility
{F4525}
3) Attempting to view cargo through glass
{F4527}
To reproduce:
1) Spawn ship core, place storage, and 5x5 plane of Cargo Space
2) Fill up the container, noting cargo visibility
3) Place another layer of cargo space blocks above, and attempt to view the cargo from the top
4) Remove second cargo layer, and replace it with a transparent block like Glass.
5) Look again from the top, you should have difficulty in trying to even see the filled Cargo
