Hey sorry for the not-very-descriptive bug report, was very tired lol.
No I'm not playing with mods. The issue was that i would build a CPU, and the manufacturing cost would be something like '$54.76', but when I set the selling price nothing would be accepted less than like 110, for example.
Anything below, and the selling price was highlighted orage in the 'New Hardware' screen, and It wouldn't sell for any profit at all.
Almost as if the manufacturing cost is displaying lower than the actual value for some reason?
