Yeah, so I wanted to turn tech-mining industry into structure. I don't know how to make proper mods, and I'm too dumb and lazy to understand it. But to turn it into structure just go to D:\Starsector\starsector-core\data\campaign and open industries with WordPad and find techmining,Tech-Mining,30,45,,2,,,"techmining, industry, industrial" and change it into techmining,Tech-Mining,30,45,,2,,,"techmining, structure, industrial"
No idea how it will affect other mods or what will happen if you already have tech-mining installed on any of your colonies, so make backups if you want to use my file or just change your own.
If anyone feels like making a normal mod out of my crappy post, just do it.
