Hi,
There is one bug, which makes my mission impossible to accomplish.

I have received a mission assignment in game to establish an orbit above Duna.

Turns out the desired orbit is of very similar orbital parameters just like Ike's orbit.

Normally it would be possible to make orbit with probe orbiting on the other side - to not to have it crashed to Ike.
However last condition of the mission assignment made it impossible - to hold the orbit DIRECTLY above Duna site - The site is directly pointed on Duna's moon Ike.

I can't establish circular orbit around Duna, as long as Ike's gravitational influence will never let me to position myself that way.
We could zero-out all the relative speed at the good spot, but if I engage my engines on the temporary collision course with the moon, to cancel its gravity and to create the orbit, it will never yield a desired orbit shape in the tracker view, that needs to be there in order to complete the mission + maintaining the stability for 10 seconds.

I've consulted someone who knows way more that I do in KSP and told me, this mission is impossible to do.
Is that right and this is a game bug, or is it possible to establish such orbit ?

I should mention: I've bought DLC Breaking Ground day prior this issue happened, and I have not started a new game but loaded my old one, where I use the DLC's features.
I am also using one outdated mod: MechjJeb2 from CurseForge
