I had 2000 points deducted today. This had to be for Week 2 as I did not submit for Week 1 until Day 4. My answer for Week 2 was cut-n-pasted from post #1 of this thread (Chitwan National Park, Nepal).
I can not guarantee, however, that the points removed from my account are related to this promotion at the moment.
Did the point deduction say 'Anywhere Challenge'?
Is there any other promotion you are doing that they could have reversed?
