The newest version causes this error when loaded, probably because the sprite of the rocket silo has changed a little for 2.1, and this mod automatically adapts to the new size while still uses the sprite derived from 2.0 silo.
Failed to load mods: The given sprite rectangle (left_top=0x0, right_bottom=628x204) is outside the actual sprite size (left_top=0x0, right_bottom=608x596).
