Funny to watch how an empire is build in 80 turns and then being destroyed
by 2 bands of barbarians in 20 turns :-]

Why can I see the whole map and all units? Does this mean you hacked
the server to give agents omniscence? I don't think this is the way
to go with client side AI. :-(

The explorer is idle the whole game, no exploring agent?

When the empire is destroyed, the last city builds settlers on
an on, which are standing idle in the city, doing nothing.

Another assert occurs after disconnect from a lost game, reconnect to
a new server and "start". Backtrace follows, core file available.
