I just finished my insanity playthrough as an adept so I could get the last of my achievements. Since this was a fresh character, I used Barrier an excessive amount. Hell, I must have used it like 50 times just on the final mission. But despite this fact, I haven't been awarded the achieve. I am currently on a low level adept, casting Barrier repeatedly hoping it will unlock but so far nothing. Has anyone encountered this problem?
I also needed to get the scholar achieve which I attempted my second playthrough. Both times I got all the necessary stuff but no achievement. The only reason I didnt get it my first playthrough was that stupid Prothean entry. Any help would be appreciated.
