You need to build objects where you can view the puzzle; there should be at least 2 of them.
And Aska buries herself in different places on the map.
I placed the obelisks, finished the map, and when I close it, it writes to me in English that the obelisks are there, but you haven't buried Aska's tear.

Regarding the editor. What errors does it display? Perhaps these errors indicate that the map is unplayable? Or maybe there are conflicts between objects? Describe the problem in more detail.
Unfortunately, now the editor doesn't want to open the map at all.
