I just confirmed personally, using the live build of 1.0.0e, the plot menu appears after Stranger gives you the objective. Though if you didn't start a fresh game from the New Game option, you will likely need to wait several minutes after first loading up with SS2 to allow it to handle all its setup.
One of the ways we made SS2 so much faster code-wise is by using a caching system, but that caching takes some time to do. We assume for most folks, that time will be masked by them doing the early game sequence - so if you skip that, you've got to give SS2 some time to prep itself.
Is it possible that the 1.0.0e archive file on the Nexus is somehow corrupted or incomplete? That's the only logical explanation I can think of right now...
I completely cleaned out my loadorder, using nothing but UFO4Patch, CanarySaveFileMonitor, HUDFramework, WorkshopFramework, SS2+ Extended and the 4 Addons, and finally StartMeUp. Started a new game, skipped pre-war Santuary via StartMeUp, cleared out the Vault, went to Sanctuary and cleared it, picked up the Magazine, built and powered up a Beacon. Stranger appears, hands me the ASAM. SS2 category in the build menu appears, without the residential plot category.
I'll give it another half hour or so, but I doubt it will fix itself, because I'm already starting to see errors in my save files (checking them with Fallrim Tools), which never happened for me with the previous versions.
I apologize for being persistent, but I believe something is definitley not right here!
(Edit: With 1.0.0d, using the exact same procedure, the SS2 setup is already finished on my mashine when the Stranger arrives and the residential plot option immediately shows up in the build menu as soon as I receive the first ASAM. And no errors in my save...)
