i'm using the split features tool to create two polygons from a bigger one. The problem is, when i save the split i have done, half of the polygon disappears. But sometimes, after doing some more polygons they appear again, and the last ones in with i was working disappear. Do you know what is happening and what is the solution?

PS: This Shape was made by other people and i don't know how it was made, neither in which program has been created.

Try checking the geometry with the check geometry tool and rebuild the spatial index.
