Freeze Nation happiness

[simple-simon]

I was wondering if where I could disable nation happiness. I thought maybe it could be set to "0" in the difficulty settings.
In 2.2.1 one could disable the civilian death limit by editing a file. Does this also apply for the nation happyness?

If this is not possible, can I just change the happiness values in the "nations.ufo" file in "0ufos,pk3". E.g. there are values for each nation like "happiness 0.5". Will editing these values change anything, like the happiness gained by doing things?

The value in nations.ufo is the starting happiness for the nations. Setting this to 1.0 will start the nations at maximum happiness. They will still lose happiness as normal, though. You can't prevent this without changing the code.
