Blueprints updated and added invoice locations 9/28/2015
*Patched 10/6/15*
WARNING - If you pickup a blueprint during a mission and fail to complete the mission i.e you revert back to a check point, there is a chance that the blueprint will no longer be available. Make sure to stop and save your game after picking up a blueprint. You can save by doing any number of things in the menu and seeing the yellow circle on the top right of your screen.
If you would like to check which Blueprints and Items you have then open your Idroid and move to the left tab (I believe its the "Mother Base" tab) and go to Encyclopedia. Then go to Documentation.
