Play the game without mods in a always running configuration, hosted on a Linux server. In the config only admins are allowed to pause the game and require_user_verification is set to true.
What happened?
When a user pauses the game on our server, for all users that are currently online, the correct username will be shown in the "xx" has paused the game title:

Upon reentering a paused game, the server seems to have forgotten which player paused the game and shows "<unknown-user> has paused the game":

What did you expect to happen instead? It might be obvious to you, but do it anyway!
The server should show, which player paused the game.
Thank you for your help!
