I tried to use the NickN mod "Expanded Home 0.4"
when i go to one of the rooms (example Kitchen Office etc)
i just get an empty concrete room
is there a way to edit them or am i missing some addon ? i cant find any documentation on it lol
edit/update: I noticed an option "Build a New Room" and was able to build a living room which replaced the empty one, but now the build room option is greyed out. is this limited to 1 build or is it on a cooldown or something?
You should read the readme.txt in the mod's folder first, it's contain the answers for your 'howitworks' questions and limitations.
...
"Before you are able to use a room you need to build it. Select "Build a new room (HE)" when at home to do so.
When building a room you can choose between DIY (if you got enough energy, fitness etc.) or hire workers to do the job for you.
It will take between 6-10 hours to build the room, depending on your choice.
If you go for the DIY route its cheaper, takes longer but you gain some fitness, intelligence, muscle etc - if you let the workers do it, its more expensive but faster.
If you constructed a second and/or third bedroom you can rent it to earn some money... Or do lewd things with your tenants. ;-)"
So I think you didn't finished the buildings and/or run out of energy.
