WHAT IS THE ENGINE OF THIS GAME FOR TRANSLATION PURPOSES
Custom made c# engine based on the .NET framework and WPF. Currently there's no direct translation support aside from editing each event manually.
While there's plans for some support in the future, I'm afraid there's no way to avoid having to inspect/edit events either way. A lot of the text is built dynamically (not hardcoded), from different mixes of sentence parts and keywords. And since English is a very simplistic language, translating such text would involve tweaking the logic that puts it together (contained in events) for most other languages.
1.10.3. economy is out of balance. Devs probably changed it to make end game possible with ten teachers and all possible clubs, but that gives middle game way too much income. Or I am running school on high rep with less efforts than before.
You do not need money cheats. Just improve reputation and don't expect to have fully upgraded school on day one.
Per player feedback funding was tweaked to make a fully staffed school possible (it basically wasn't before). People wanted a better reward for running a successful school, but if the result is too generous - I recommend actually pointing that out in the relevant forum threads (since we check F95 like every few months). Since none of us actually have time to test long term stuff.
I feel your pain, I'm not a futa fan AT ALL. I've tried setting it to 48% male, 1%futa, and 51% female and it still leads to a very large amount (likely more than 1%) but if you're willing to take the time (and it WILL take some time) and cheat a bit, you can view who's who when they're in your area and change it. Simply go into the debug console, go to current location, then match the green names from the area to their name in the console: click body parts near the top and remove penis size and testicle size, then go to gender a little lower and switch from Futa to Female and you're good to go. Rinse and repeat anytime you see Green in the area your in. I would just avoid doing it to either of the custom Futa's (the editor and Sierra) just to avoid breaking anything in game.
The gender mixes do work. And it should be safe to lower futa at least, it's male/female mixes that require 3-5 of each per specific events. The issue you're seeing likely has to do with the fact that school enrolment tries to balance the genders until it runs out of candidates (1% of +-625 is about 6 students). There's an Info Panel tab (on the player) that can show you the gender mixes (if you have high intelligence, or tick 'Enable Debug Events' in debug).
Also, there's actually an option in the Map > Config that lets you remove futas from an existing save. Though that reminds me, I should probably update it to apply the name change like drugs do.
