I am currently level 7 with my jeweler, however, I did not receive achievements for acquiring my jeweler, and leveling my jeweler to level 5. Below I've provided a screenshot on this bug. I have noticed other bugs like after killing Butcher on Hell, I noticed that I didn't get my achievement for Nightmare, but, those are easily acquired after the fact. I just won't be able to "reacquire" Shen the Jeweler, or even regain previous level.

Thanks for the help, and hopefully this gets solved soon. :D
