Broken contact links in web interface

[Peque]

I recently upgraded to NC 13 and it seems some links in the Contacts app are not working in the web interface.

When I hover the contacts in the contact list (no click) I see 2 different types of links:

1. https://domain.com/apps/contacts/#/Group/e5c9a57f-d84c-4b8c-a59b-ee742e1b42a1
2. https://domain.com/apps/contacts/#/Group/https://User@old.domain.com/remote.php/carddav/addressbooks/User/contacts/2EAF6525-17ADC861-38D6BB1D.vcf

The second link type is broken (i.e.: if I click it, I get redirected to the Group's default page, which is the first contact in the group).

This did not happen before upgrade. Is it a known issue? Is there any way I can fix that?

Please, tell me if you need any further information.

Notes

• The contact information is intact and correct (i.e.: no information lost). Only the link is broken.
• Contacts that have the second-type link are older (i.e.: were created maybe long time ago). Contacts that have the first-type link are all more recent contacts.
• The second link contains "old.domain.com" too. The domain change is, however, something I did some time ago, before even upgrading to NC 12. And I didn't have this problem with NC 12.

@juliushaertl Ok, they say "Migration and CardDAV issues belong in the server repo!" so thought this would belong here. 😅
