Construction Revert to VAB causes radial parts to disappear or causes unassembled ship to appear in VAB floor

While building ships containing boosters mounted radially using the multiplier function (x6 in this instance), I would try to launch.  When I revert to vab, only the original booster stack is still mounted radially with parts of the others missing completely.

At other times, reverting to VAB would cause the ship to appear below the floor of the VAB in an unassembled state.
