Bug Problem with SyncOrbitMFD and UCGO Arrow

[Kaito]

Yesterday, I tried docking with the arrow in LEO, which I put into orbit Via scenario editor. I matched altitudes, and then I tried using SyncOrbitMFD. The results are as follows:
Just before crossing reference point:

After crossing Reference point:

Obviously, something is wrong. I later tested SyncOrbit with the ISS, and it worked fine.

So then, I try to use LaunchMFD to get myself into a proper orbit. The results, about 5 seconds after MECO:

Obviously, something is going on. I'm not sure if this is Arrow related, but I have a feeling it is. If anyone can help, it'd be appreciated

Not sure about the LaunchMFD issue, but the SyncMFD issue is caused by the fact that you're losing ground to the Arrow (it's pulling away on average b/c your orbit is higher than its orbit and it's "ahead" of you in orbit") and your closest orbit that can be calculated by the MFD is the one you're currently on. Hope this helps.

Wouldn't you normally launch to your target when it was close to above your launch site, as opposed to on the other side of the planet?

I matched my altitude on one side of my orbit to that of the Arrow's. I did the same docking procedure which I normally use.

I launched when LaunchMFD told me to

I don't recall having put a "MessMFD()" function in my code. (maybe "problem" would be more appropriate and more polite ?)

Howewer the Arrow don't do anything special to trajectory or MFD appart its uncomon weight and inertia. (which might cause problem to some MFD)

Anyway I used IMFD for long trip without any problems, so I don't know.

That orbit isn't in the same plane so I think you are going to have considerable issues.

Which one, the last one?
I know that isn't in the right plane, but that is where LaunchMFD told me to go

I suggest you read the Go Play in Space tutorial first, then apologize to DanSteph.

Kaito - where did you launch from and what parameters did you enter into LaunchMFD?

This isn't an arrow or UCGO problem, possibly a bug in Launch MFD or a misunderstanding of launch mechanics but we can fix all of that.

Sorry DanSteph, topic title changed. I assumed it was being caused by the Arrow because that seems to be the only vessel that has that problem

I suggest you read the Go Play in Space tutorial

I have rendezvoused and Docked numerous times before, so I know the procedure. I've read Go Play in Space numerous times, and never had this problem.

NOTE: The third picture is completely unrelated to the first two. That was just showing that I was having some other problems.

In LaunchMFD, i typed in target "Arrow", then launched when I was told too. I also followed the correct heading (that white highlighted one, heading 348), and followed the little "+" indicator. I've never had problems with it before.

I'm getting exactly the same problem as you do Kaito, I tried doing a rendezvous with the Arrow multiple times using the Sync Orbit MFD with no success.

I did put the Arrow in my scenario with the Scenario Editor in the same way you did.

I'm uploading the scenario so if anyone wants to take a look at it and try to rendezvous, please let us know

Just take the second azimuth provided by launch-mfd(the non-highlighted one).
