I wonder if it's a bug. After all, the plow has to push not only the immediate nebular clouds, but also the whole nebular width. Think of it as a "domino effect" on the nebula. I guess you have to ponder the use of the Plow if you want to cross a very large nebula right across the middle. No gizmo is ever perfect...

I tend to be extra careful with the Plow. When I have to cross large nebulas, I try first to "divide" it in smaller chunks through my first travels (criss-crossing and working close to the edges). Then, crossing through the middle is a breeze.
