So here I am taking advantage of everyone dumping their silver nuggets and finally trying to get my blacksmith to 50. So I spend 200 company seals to get an engineering manual to help boost SP. When you use the manual it starts a timer that gives you 3 hours and at r46 is giving me about 150 extra SP per synth.

Seeing how great this is I prepare for 3 hours of hardcore grinding. But about 40 mins in it goes away and I get a message that says something like you are no longer under crafters grace(cant remember the exact message). WTF!!

Nowhere in the items description does it say anything about an SP benefits limit. I feel kinda ripped off. Anyone who purchases one of these is going to buy it with the intent to use it while grinding to maximize SP. But it won't even last 45 mins so why put a 3 hour timer on it. Maybe a day will come where company seals are infinite but right now they are precious. Hope the day never comes when I come up 200 seals short of some epic weapon or something.

I didn't test the DoL manual but I'm going to assume it has the same issue though it might take a bit longer to hit the SP cap.
