They are still bugged as follows:
On one character I have done all missions on the day of availability and completed them successfully, so no issues as long as they are completed every day. I will be able to test the weekly resets starting today.
But on another character, I did not log in for 2 days, and as a result I am missing the missions for those two days (Thurs/Friday) for this week. It appears as if when you skip a day the mission disappears upon the next reset.
I think thas is intended. You get one daily a day. If you don't complete it that day it drops out for the next days daily. That's how I believe it works, BW can correct me if I'm wrong but that's what I got out of it.
