The title says it all,I have the side quest in my journal to ask gunmar about extra work or something like that.The quest arrow is above him but when I speak to him it's the three basic things(Smith training,troll buying,store).I have done ancient technologies for Sarine and completed the dawnguard questline and the Main questline so I'm pretty much stuck.
