Python MPB interface seems to round down for lattice vector size

[DerekK44]

When I create a lattice object using the Python MPB interface and have a lattice vector component less than 1, it seems to round it down to zero. For example:
geometry_lattice = mp.Lattice(size=mp.Vector3(0.25, 2, 2))
ms = mpb.ModeSolver(..., geometry_lattice=geometry_lattice, ...)

In the output file it then says:
Lattice vectors: (0, 0, 0) (0, 2, 0) (0, 0, 2)

which creates all sorts of issues during execution of my program. It works fine using the Scheme interface, so I am guessing it's a bug / rounding error in the Python implementation?

Thanks!
