Never had this particular issue. Seems everything was going fine then this.
The bottom 1/2 inch or so printed normally, there should have been another inch that looked exactly like the bottom part that printed ok.
Instead the upper last inch came out as a bird's nest.
This exact same file printed fine previously so I don't think it's the x3g file
