What. So you are telling me, it was a problem with your setup all along?
Mh, if moving it to the directory fixes it, moving it around in MO2 should work too. Not in the load order, in the main mod list. Though I'm not sure if stuff in Data counts as highest or as lowest priority...
But, on the upside, I did find some actual bugs while looking into this: not only isn't my adv.ind. plot properly hidden behind IndustrialRevolution, neither are IndustrialRevolution blueprints themselves.
(The blueprints themselves are in SimSettlements.esm, the addons only include their assets).
Oh well. I'll just make an update to fix the IR requirement on my end.
