damn this needs updating. I've noted that playing as barbarian factions with this mod on seems to make the warrior code technology tier bonuses cost me 5/10/15 food....PER province. I didn't realise it was costing me until I decided to finally upgrade my ship tech as the last thing I needed to research then the next turn BAM -287 food from unlocking tier 2 and 3 "bonuses" at the same time.
