MechJeb landing guidance not accurate?

[Kerbal Productions]

Recently I have been using MechJeb's landing guidance feature, but it just actually followed the path of the booster without doing some burns (except for the last burn, the landing burn to decrease speed). What's wrong with MechJeb?

Thats rather sparse on detail.  You need to be specific as to exactly whatvyou did, etc.

I did an 80 km hop test of a prototype, and I kinda went into sub-orbital trajectory. I turned on landing guidance but instead of doing boost back burns to the KSC, it just followed the path it did before I turned on landing guidance. I landed safely in water tho. That's what happened.

I have never used that feature but i know sometimes Mechjeb needs a ''wake-up'' call by warping(physical or normal) for like a second and back to normal and see if it gets any better and does what you want to.

So, I actually have a post here regarding my own issues with MJ not doing burns when using landing guidance.  You pick the target, click land at target, and nothing happens.  Well, I did some testing, and after I upgraded the R&D building to level 2 and got Advanced Flight Control, it now seems to work.  You can see what I've written on this here:

I'm in Sandbox, so the R&D is at max level. But still, that's the problem I face,

Ah.  I don't play in sandbox other than to test rocket designs, so I have no experience with MJ there.  For my issue, it was in career mode.  But it was the same issue you experienced, which is why I responded.  Might have to go to GitHub and report this as a bug...and then hope the developer is still around and fixing things.

Move on, guys.

The MechJeb is now kinda ok, but in a weird way. So, yeah I have problems still with MJ but now I'm getting over it by part editing.
