Sphere shapes created with minihud are not symetrical. It does not matter if and what block snap mode is used. This is an issue for all sizes. I am using minihud to create outlines for basic shapes for buildings, but was unable to use it to create a perfect dome. I had to use another mod (carpet mod) to create a sphere shape in creative and then create a schematic from it with litematica. Placing the shape outline with minihud would have been way faster.

Duplicate of #215. I believe you can use the "Adjustable spawn sphere" for non-crooked spheres for now as a workaround, until I fix this at some point.
