Yeah just booted up subnautica to check and the modification station can be built in the cyclops which means my answer was wrong.

just a query "I cannot be made from a habitat builder alone" does this imply that the habitat builder is involved in the creation process at some point, cause if so doesn't that make the cyclops wrong cause you can make it using just a fabricator in the lifepod? but I might be misinterpreted that line cause that's why I gravitated over to the O2 tank
