How do you get to the next level after dessert?

1

I completed all of the free levels there are and I can’t go to the next level after the desert of Sarven.
Any help?

2

Have you completed Clash-of-clones level?

Where is the Clash of Clones? I looked thru the map and found nothing.

Apparently the map says that I haven’t completed Sarven Shepherd ( i did)
but it didnt give me xp and gems and didn’t unlock the location. Replayed it and now it’s fine!
