This sounds like a bug. I played lithoids with the mod myself previously without this issue. Might be related to 2.8 patch changing something I did not into account. I'll try to get a test game going as soon as I finished improving the admin cap management.

Hey there, I just looked into it and I can't reproduce it.
Are you referring to farming districts or buildings (or both)? Is you empire any special kind/modded/mixed species?

Do you have the "Force Show Income Options" enabled? If not could you enable it, and check what values the food income in the main menu are set to?

I am referiing to it making farming districts, I wonder, is their an email I can send a video to, basically a screen recording?

I did not know that was an option or even see it, i want into the policies to start changing minimums and what I would like, where would I see it?

Update: So i went in and forced options, which food was their, disabled it, and had No problems :D. The only thing I did not see which I would like is a research option and maybe a custom number but I do understand the difficulty in programming so over all very well done :D

My guess is some mod/species combination causes a conflict, it would be nice to see your empire pops and civics/ethics to get a grasp of whats going on.
Research based on a "limit" is difficult to implement due to engine limitations. But I believe that dedicated research worlds are the best option anyway due to increased efficiency.
Custom number input in Stellaris for modded dialogs was something I explored with +/- buttons but it turned out to be very problematic for various reasons, one of them being the ability to display a number from a modded variable.

When I have some time around the holidays I'll take a look at the menu for gigastructural constructs game-setup phase where you choose which megastructures to enable. It might be a good way of doing things and creating a more visually appealing and less nested-dialog style menu. But that is not a primary goal, because I think the menu controls work quite will right now and allow a lot of flexibility. I'm more focused on better unity/admin cap management right now.
