Desync when rejoining long multiplayer game

[lucasdowman]

Hi everyone,

I’ve been playing a long Freeciv multiplayer match (around 6+ hours) with friends, and we noticed something strange when a player disconnects and then rejoins. After reconnecting, their game seems slightly out of sync — for example, unit positions or city production don’t fully match what other players see.

We’re all using the same version and no mods, and the issue only appears after long sessions.

Is this a known limitation with long-running multiplayer games, or could it be related to server settings (like autosave or turn timeout)? Also, are there any recommended settings or practices to prevent desync when players reconnect mid-game?
