Last night i was working on a plane and while manually entering rotation a single prim in the vehicle would turn to a box rather than the shape it originally was. When this happened i thought it was a fluke or I screwded up while editing an item. then i went for a rade with a friend and when i came back, i landed and was dragging the plane to its nice parking spot. When i got it on the spot i was straightening it out .. again while manually rotating it via number untry rather than the slide wheel and another different prim turned into a box. Oddly enough when I change the box into what ever shape it was originally it still doesnt fir it as it changes cuts/hollow and angles of the prim.
Anyone else have this problem? Is it a known one?
Thanks all.
