Yes. No. Dunno.
Looks like a race condition here. The server does what it should: it fills
up the players list with AI players. When a new human player connects, one
AI player should be removed. This does work in some cases, not in others.
Then the newcomer is "detached".
Start civclient, new game, aifill 30 (gives 1 human and 29 ai), then connect
with another client: it is "detached" (btw, the new, second client also has
command level hack, but a reduced menue in pregame screen. Intended?).
Then if you pick a nation, the server crashes:
Core was generated by `civserver -p 5556 -q 1 -e --saves ~/.freeciv/saves'.

Here a case where it works ok. See 3rd line:
Start new game, aifill 20, connect with a second client:
Welcome to the Freeciv version 2.1.3+ Server running at karl port 5556.
AI19 has been removed from the game.
AI Mode is now OFF.
You are logged in as 'chrisToo' connected to chrisToo.
