Undo this:
   lsend_packet_generic_empty(&game.est_connections, PACKET_FREEZE_HINT);
   send_all_info(&game.game_connections);
+  show_map_to_all();
   lsend_packet_generic_empty(&game.est_connections, PACKET_THAW_HINT);

It was inserted to have a fair comparison with the server-AI. And also
to concentrate on one thing (city placement and settler production).

There is an exploring agent but nothing to explore. If you remove the
show_map_to_all the unit will also explore.

This is an bug.

This is one of the cases where not all state is saved. Basically don't
disconnect or load ;)

BTW: you can disable the whole AI and play a normal game with agents
(you can for example watch a trireme exploring the ocean) if you
comment the register_agent calls from master.c, tma.c and turn_done.c.
