hi. i am making a 3d game and while i was trying to delete an image point in a 3d object,construct 3 sent an error message and made me save the .c3p file but when i tried to re open that file its layout was empty.i tried to even zoom in and out to see the edges of the layout(the gray part) but it was all white.none of my objects were being shown(i couldn't select them either).
