I’ve received the email for next level.
After refreshing the page desert, sarven brawl was visible and accessible, but nothing more after Yakstraction (that was succeeded.
I need to use the email shortcut to access it. (sorry, I did not try to redo DecoyDrill).
After succeeded in Desert Combat, next red point appears normally.
(just for information)
