Aligning cubes with grid


Some days ago before the 0.69.0 version I was able to align perfectly some cubes using the grid option from menu. A sequence of alt duplication of the cube and moving the new one with the desktop mouse did do the task perfectly.

Now when I’m trying the same alignment it really does not work and the cubes are aligned in a semi-random way (!). Am I the only one appreciating the very good work of the grid aligner?

As you can see it seems impossible to make all the three cube to be horizontally aligned …
