GSX pushback braking the nose gear

[couger]

So I’m doing a pushback at ymml on parking 3 cargo using the 747 8 pmdg.  Pushing back tail south which is a very sharp turn.  But it’s real turn as I did it when I worked for qantas freight.  Anyway it pushes the plane back no problems but then when I go to taxi suddenly the nose wheel hooks hard left and goes into the grass.   

Any help?

That's why you can do custom pushback routes.
