The current version of the Careers mod without any of its add-on modules doesn't have many (like maybe three) sets of commands associated with it. The next version up, currently in beta testing, will have more. The base mod alone is mostly a loader for the modules and any custom careers made by NRaas or other developers; we started getting fancy with it much later in its development cycle.
But the fact that you even have an NRaas > Careers menu at all for the mod was what I was looking for.
Okay, so your mods and packages Framework is functioning properly. That leaves us with the rabbit hole rug question. Had you decompressed (un-rared) the file from Misty before placing it in Mods\Packages where your other package files are?
