Ok, now I know what food is good for wellness. Btw does killing the mutant hunter still count as humanoid monster? Although I did take a huge blows on the wellness by killing the hunter, just confirming.
Also try checking the Bug report thread, I posted a kinda major bug if you need to improve Helena relationship because that doesn't count to Helena.
Edit: I think you misplaced something. Roman doesn't teach you electric stuff, it's Tadeas the alchemy guy. He teaches you "basic electrical theo" that enables me to use electric and build electrical grid, whatever that is. Roman only teaches you machining table using (The gunsmith also have that) and steam engine thingy, can't really read the full description because most description in the game is kinda cut off because of how long it is.
Edit 2 : I got the electric skills from Tadeas but how do i make it? My house is still a tent btw and i tried to put my old fridge on one of the workbench slot (cooking, recreation, and that kind of stuff, the recreation slot is not working tho, not like empty but just not giving me the option to see if i have it or not) in hideout but no option to put the fridge
