Describe the bug

Using the offset mask with a sphere brush only seems to work around 50% of the time

To Reproduce

In this example I'm using red tulips, but it also happens with other blocks

1. //br s red_tulip 3
2. /mask >water
3. /gmask 0

Using the brush (sometimes) leads to semi-spheres of roses:

Expected behaviour

All roses should be flat
