Help with rover fix mission on Minmus

[radicaled]

I'm doing one of the missions of the new pack.
Basically there is a rover on Minmus that needs to be fixed and then moved to a waypoint.

So first I put the solar panels and the batteries, move it, but it doesn't complete the mission.
Later I added the command  seat (I thought that a kerbal need to move it), move it, but again doesn't complete the mission.
I run over the waypoint several time and use the science junior experiment, but it doesn't complete the mission.

Any suggestion, something that I'm doing wrong?

There is a bug where the waypoint is underground and thus unreachable. Seems like what happened there.

Open the debug menu, find the contract and complete it there
