Okay need a bit of help with S&V: I get that ships start with certain modules Installed, but I can’t for the life of me figure out what the Available modules are supposed to be. At first I assumed it must mean that those are the only available modules for purchase with the group’s beginning upgrades, but later on it stated that the Cerberus could start with the targeting computer, even though it’s not listed as an available system.
