Caravan window is empty in multiplayer

[Jayas4]

When trying to form a caravan in multiplayer, the caravan window becomes empty after the first caravan is sent.

The very first caravan works normally.

Any attempt to create a new caravan afterwards shows no pawns, animals, or items.

The list is completely empty, making it impossible to send additional caravans.

Steps to reproduce

Start a multiplayer game.

Click on Form caravan.

Observe that the list is empty (no pawns/items appear).
