There are some weirdnesses in there at this point, one of which I took advantage of to fix this but I hope will be fixed in later versions.I'm surprised by how much depth there is in the character building system. Very impressed. Took me awhile to get a feel for how things worked but there's a lot of options.
One minor gripe I have is with the food system. I haven't found any way to influence my slave's likes and dislikes when it comes to food so I find myself just selling slaves that have a bad combo there that just doesn't really work. For instance you could get someone who likes meat but hates vegetables and grain which would make it impossible to actually cook anything they like. The best you could do is neutral. On the flip side, unlike your own character and your first slave that you can customize, you can get new slaves that randomly have zero foods they hate.
How I would prefer it: option at the mansion to harvest main food types immediately
How I worked it currently: Fish are the most expensive food option. Meat is the same cost or buy, bread or veggies are 2/3 cost. Sell the excess fish and keep the others stocked by buying at the shop. Set the char's priority to "high" for their favorite and just make sure you keep an eye on supplies.
