I just recently entered grade 5. I already reverse engineerred 20+ green armorings of the same type, and I still do not have a blue schematic of it. Whereas in the previous grade it sometimes only took me 2 or 3 attempts to get it.
Did something go wrong in the last patch and we are currently unable to receive grade 5 blue schematics from reverse engineering ? I put all the recources into it that I can get my hands on but it feels like I am getting nowhere with it.
Seems you have bad luck. I RE'd two greens, and 1 blue to get my reusable tech surgeon medpack, for example, but I've RE'd a good dozen blue level 21 implants without getting a purple recipe.
