freecol v0.11.6 on Linux/Fedora 31

Description

NOTE: I'm using FreeCol in French, so the name of the menus can differ slightly as I translate them into English on the fly.

On a hotseat game (2 clients on the same computer, one as the owner of the game), with a previously saved game, Player 1, the owner, opens the saved game and waits for Player 2.

Player 2 clics on "New game" and chooses "Join a multiplayer game" with server 127.0.0.1:3541. He also chooses "Player 2" as his name.

If Player 2 chooses his own previous nation, an error message tells him that the username isn't present in the game.

WARNING: ServerAPI. login error, messageId: server.userNameNotPresent message: Player "Guillaume Ier" is not present in the game.
Known players = ( Player 1 Player 2 Louis XIV Élizabeth Iere )

Desired behavior

Use the name specified in the "Name" field as the username instead of the default name for the nation.

Why am I sure the problem comes from there?

If Player 2 chooses another nation, when prompt, he can take it without a problem.

Workaround

Unzip the saved game, change name="Player 2" to name="Guillaume Ier" and rezip the saved game, but seriously, that's not even an option for lambda users.
