I just completed 2 JP in Diessa plateau and I didn’t get a single point in monthly jp achievement even thou it only says it has to be discovered, not completed. ( wall one, and one right above it )
Anyone else has this problem?
I will go on and try others, and eventually complete it, but some are just not giving points.
You should get credit for a jumping puzzle before you start doing it; in other words, you don’t need to complete the puzzle to get credit towards the monthly achievement. That also means that you’ll want to check your progress on the achievement before you start the jumping puzzle to make sure that you haven’t already received credit for it.
If you’re certain that you have not received credit for a jumping puzzle, please let us know which ones you suspect may not be working right. Thank you! 
The WintersDay one did not work for me!!
So I just found out that the Wintersday JP is the one exception that is designed to not give credit. My bad. >.>
