I have now tried to scan several pieces of the suit fragments (6 fragments if I remember correctly), but I can't seem to get the blueprint.. It says I have completed 25% of the blueprint, and I have tried going back to the places where I can find the suit-fragments but they won't spawn again. Is there any way to get the blueprint without having to start a new save?
You're scanning the small fragments from wrecks, these only contribute 5% to the blueprint. Instead you should go to the Prawn bay in the Aurora where you can find large fragments that add 25% to the blueprint.
