"Stranded Ship" mission cannot be completed

[pepoluan]

Originally reported this in game's repo, got told that this is an issue with the UrsaPolaris plugin. So I just copy-and-pasted my report.

Describe the bug

So I visited Hestia in Talita, met with good ol' James again, we fetch his ship "Marius" on Danoa, and went to Alnitak...

But everytime I landed on Farpoint@Alnitak, game complained that I left James behind!

To Reproduce

Steps to reproduce the behavior:

1. Start the "Stranded Ship" mission
2. Go to Danoa and board the "Marius"
3. Go to Alnitak, wait for "Marius" to arrive, land on Farpoint
4. See error

Expected behavior

Mission should've continued (or ended?) at that point.

Screenshots

Prior to landing, as you can see I have "Marius" with me:

After landing, game complains that I "left Marius behind":

• OS: Windows 10 Pro version 20H2 build 19042.804 with Feature Experience Pack 120.2212.551.0

Update

So I quit the game while landed on Farpoint.

Shut the computer.

Today, I started the game again, and I see "James is grinning ear to ear" (i.e., the mission progressed)

Don't know why it got stuck yesterday.
