I am having a problem when loading my Tython ship model into PCS2, when i export it to DAE and load it up, at first get to errors for 2 of the turrets "Instance_geometry not found for turret37" and wont import the turret. This is a first for me, never had this error before. Then when the model does import i then get this problem

The large bottom turrets now have rotated inside the hull, and i dont know why it keeps doing it with 3 of these turrets. I have tried deleting them and replacing the bottom turrets but this always happens and is starting to annoy me as i cant seem to solve it.
