When you build liquid/gas pipes through the top wall of the space farer module, then deconstruct them, the resources are dropped on the top of the module where they cannot be accessed. When you build through the right wall, and deconstruct, the resources fall into nothingness and do not appear below the rocket platform as would be expected. Picture below showing the issue.
Build a pipe in the right wall or ceiling of the spacefarer module
Deconstruct the pipe
Resources are either trapped outside above the module, or dropped into the void
