3) Upon opening any ship with multipart turrets and/or radar dishes, say the orion, selecting SubObjects>detail-0>turret01a will select the base of that turret. All the properties display correctly, but the axis is "none" for all rotating bases. In fact, I just then noticed that the non rotating turrets actually have the X axis defined, though they're set to No Movement.
Essentially, in the second level of heirarchy (the turrets), stuff that is supposed to rotate is set to Movement Type -> Rotate but the axis is set to None. Stuff that isn't supposed to rotate is set to No Movement, but they have the X Axis defined as the Axis of rotation. This same case applies to non moving stuff like the LODs and debris.
Meanwhile the third level of heirarchy (the turret arms) are fine on both accounts.
