• This isn't a security bug (if it is, please email security@lockdown.systems instead)

Describe the bug

When saving DMs, the users don't appear to be getting saved. Instead of displaying info about each user, it's just showing the user IDs.

I think this is a regression bug.

To Reproduce

Steps to reproduce the behavior:

1. Build database from scratch, making sure to save DMs
2. Browse the archive

Expected behavior

It should show the name and avatar of the users.
