You should send them your saves with the edited high food/slaves amounts + some minor instructions on how to increase/decrease the values easily (like doing a specific rite) and that should be exactly what they need to add the options, i'd imagine.
The money option is the option 1 - Mega Favour.
It's not call money option because in the game Total War: Warhammer 1, each faction have a different name for money. 🙂
Yeah I believe "Favour" is the currency that Norsca uses. Favour of the chaos gods specifically.
For other factions such as Empire, Bretonnia, Lizardmen etc. where you see a coin, the game calls that "funds" or when hovering your mouse over all your available funds it says "treasury"
I however wouldn't mind if someone called it money, gold, cash or whatever. People should probably know what you mean by that.
Also. I've run into a weird little problem in one of my playthroughs where I accidentally hit the key for mega influence, playing as Skaven "Clan Mors".
I completed a quest battle and after that I was spammed with a literal endless popup of "influence gained" in absurd numbers.
Not a problem for me personally, I just reloaded a save and was good. Just a warning to anyone else.
Everything else is working swell for me, although there are a few nitpicky features I think would be nice.
Unlimited blessed spawnings for the Lizardmen would be cool. Allowing you to instantly spawn blessed units, if each of these could be set to 99. That would be cool. (They reset to 10 after ending a turn)
[I've personally been able to edit values for some blessed units in one of my playthroughs. But I am an absolute amateur, and I can only do it after a few are available. However lots of fun to play around with.]
Reset Rite cooldown, allowing you to perform rites immediately bypassing the often 30 turn long cooldowns.
"Ritual resources" (or whatever you want to call it) such as Warpstones (for Skaven) and Ancient Plaques (for Lizardmen) to faster progress the rituals.
Those are just a few on my own personal wishlist, with those at the bottom being least priority.
