There is a column of 20 "default cubes" on the plane static mesh (there is no any gaps between cubes and plane; cubes are precisely align by X and Y axes; plane and cubes are not rotated). Each cube is "rigid body" and has "box" collision bounds, all other settings are default (from Blender installation). After BGE starts, each cube has tiny movement, and the whole column becomes curved. 21-blocks column cannot stay at all.
With "Physics -> Damping -> Translation" option = 1.0 cubes and column keeps stability, but acquire unnatural behavior (not falling duging bumping by sphere).
Is there any way to create stable column with rigid bodies (it stays upright and keeps natural physics)?
