Broken: (example: 2.75.x Release Candidate and dailies)
Worked: (2.74 Site Download)
When creating a particle system and selecting Volume Mode AND Grid Mode and let's say a cube as particle object,
the cubes don't fit inside the particle system's mesh. It shows a 3d grid of particle objects to form a cube..
Saving the file in 2.75 and reopening in 2.74 shows the erratic positioning, but after switching from another mode, back to Volume Mode, shows correct behaviour
