Description
I think the vertices of the polygons do not have have the exact same coordinates. I performed the following test:
1. Create the hex grid,
2. Run extract nodes
3. Try to remove duplicate geometries
almost no points were removed because they differed somewhere on the 8th decimal position.

Just tested: extract nodes creates layer with 7980 features, after Delete duplicate geometries I have 2416 features

Should probably mention that the layer CRS was WGS84.
