== Bug confirmed and recorded ==
I am currently testing various things to re-create this bug
I usually take screen-shots of my competed schematics as well as keep data in the form of an Excel spreadsheet of my completed schematics.
My Synthweave 400/400 is doing all the Re-engineering Green > Blue > Purple to get the schematics and has lost about a bunch Purple schematics who knows when, but recently.
I've completed doing Heavy Armor and Light Armor, and currently doing lower 30's Medium Armor when I noticed I had lost ALL
my Purple schematics I got from...
(Data from spreadsheet)
Level 29 Medium Boots and Headgear
Original Green : Ceramic Alloy Boots, Ceramic Alloy Headgear

All my green and Blue schematics above are intact (at this moment), and lost all the purples
I also took a screen shot of all my schematics as of Thursday, November 22nd, 2012
The schematics I lost were done After
the F2P patch went Live.
