While we're on that topic, a few oddities I noticed as well. Some of these are cases of multiple conflicting sources where I don't know who's right.
1) The "Religious Acceptance Program" investment claims it toggles on the "Ivalans in Rodak" Switch, when that's an entirely different Investment. I assume it's supposed to toggle "Religious Acceptance" instead.
2) The actual Ivalans in Rodak investment (specifically the non-New Religion version) claims that it increases "Ivala" RP by 5, but the Calculator claims it increases it by 10. No idea who's right here, or if that RP value actually means anything or not.
3) Round 1 AriGarda investment lists "Helps during the Horde battle" twice.
4) Reference 38 says "Bride Repair", which is probably a typo unless there's some wedding maintenance investment I missed somewhere.
5) Reference 112 (Min's Trade Route Chapter 5 Country Stat boosts) claims that it increases Zirantia Score by 5, my understanding is it's supposed to increase by 3.
6) Under the Round 6 section "Cycles and changes in investments" it says "Several new investments become available in Tak'kan and the Tak'kan", I assume the second Tak'kan is supposed to be the Chalice States.
7) Under the Headquarters section, it claims that the Supplies Upgrade investment requires "Lynine Back OFF", I assume that should be On instead.
8) All the Yhillin HQ Decorations claim they require Yhilin Final OFF under Condition, I assume this is supposed to be On.
9) Reference 233 mentions Orcish Democracy when it's supposed to be about the Orc Pools.
10) Crystal Refiner should mention that it helps during Incubus War Aftermath.
