That's correct, but that's not what this option is about.
It's unlimited for how much you can really put in the settlement.
(You know? That yellow/green bar on the top right?)
This option nullifies it, and you can put God knows how many beds without the bar rising.
Of course, I haven't tried the trainer out yet, and going to try the option soon!
Wizard, no Reload is not crashing my game... just infinite ammo... should keep no reload on.
