Thanks killer7, I've got it finally, I had one favor, the game went back to the same as it was when I first started playing, the "truestory" patch has gone, again it says as landlord, landlady, tenant etc. And now there is nowhere I can enter the code again, is this how it's meant to work or it can be changed...
Incest was removed because it's against patreon TOS, dev can't talk about it but a modder made a patch for it, you can find it here: https://lewdpatcher.com/game/my-new-family
