Almost every single time I jump into this sector to dock the jump puts me directly in front of a huge asteroid. Usually too close to avoid ramming it. When jumping in damaged badly and under full speed I hit hard enough to take further damage. Any way to scoot the jump in point over a thousand meters or so?

The point where you pop up in a sector is based on the sector you jumped out of. Try jumping to an empty sector in another part of the system before jumping to L-12.

As far as adjusting this to avoid the problem in the first place, the devs would probably find it more helpful if you included the coordinates you're jumping from.

Pretty much anywhere north of the sector. I run some hive skirmish missions out of here. Most if not all that I return from drop me in front of this dang floating boulder.
