Lo-Fi Games

I think developer's usual stance towards programs like CheatEngine is "Use it if you need to, but if your computer explodes it's not our fault"

Yea, I Well, it seems you are correct in how to activate them. I started a new game to test the advice, and it turns out that the blueprints on my main save are blank, simply named "Blueprints" and "Blueprints large", with no buildings assigned to either of them. Time to go file...

Glad I came here, I have the same problem. Started a second save and my blueprints have names now. I thought I was missing something XD
