This is most noticeable when Mun landing - (no atmos)

I'm assuming its the multiple stages that's the fault!

Assuming you have a stage that got you to the Mun with a little fuel left, and that the last (capsule) stage engines are a lot less powerful...

It looks like MechJeb is assuming the engine has the same power (after separation) as the previous stage - resulting in sufficient contact velocity to spoil any Kerbals day...

Can i just ask if you can make the Landing Autopilot a bit 'smarter' i had
a highly skewed orbit and was not circular by any means, i told it to land
below the periapsis to slightly save on fuel but instead it landed below
the previous apoapsis.

Someday we might make the landing AP smarter and try to take into account
stages, but it would probably take some effort to code.

Yes, "Land at target" will have problems doing a good deorbit burn if it starts from a highly non-circular orbit. In your situation I suggest circularizing your orbit at periapsis and then activating land-at-target. This should still be reasonably efficient, as you are doing your burns low.

Or turn on landing prediction, deorbit and fine tune your approach yourself, then turn on land anywhere under a minute out from the suicide burn counter. This has the added advantage of making your landing even more fuel efficient as land anywhere (in my experience) does not come to a full stop above the terrain before final approach. I haven't tried "land at" in this scenario, but it may work as well.
