I'm sorry I didn't realize you had a different problem from the OP. The original post includes a picture which shows that all the quests are completed up to and including week 4, and that's what I based my advice on.
Just make sure that your Reaper's Rewards info shows that you've completed all your quests, and you're good to go.
I thought you had also finished the quests, since you were posting in the same thread, and just didn't get enough points. If your Week 4 quests aren't all finished and checked off, even though you did the things you were supposed to, that's a bug that needs to be fixed and the advice I gave doesn't apply to you.
