Ok, just when I turn my simple cubes into rigid bodies. A lot of them move aorund, a result you'd normally get from weird interpenetration, except they are just being created , no simulation has run yet.

The cubes are made from one cube following a motion path, duplicating cubes along the way to create a nice curved row of domino stones.

I can reset all translation values back to 0 and they will all be in their correct position again, but when I opened a saved file or run a simulation, they all explode again.

Any idea what could be causing this and what could be done to fix it, so when i create a rigid body it doesnt go crazy even before simulation?
