Do they happen to join a specific settlement and does this have set up anything out of the ordinary default values, for example in the immigration desk?

Do they happen to join a specific settlement and does this have set up anything out of the ordinary default values, for example in the immigration desk?

I just had to question the affected player and he answered this:
They logged in. Selected a spawn point. It was our "main spawn point" that belongs to a global federation.

Here is the immigration policy of this settlement:

The only diffrences from default Immigration Policy are:

• Allow Child Settelemnts to Secede: False
• Children Settlements May Annex Each Other: True

Additional information:
Immigration Desk is present. It's standing outside and its force enabled (/fe) so people can spawn outside the building.
