Player objects were removed from the players dict on quit/disconnect
but never removed from zone._contents, leaving ghost * markers on
other players' maps.
Player state is now saved when using the quit command or when the connection
is lost unexpectedly. Ensures progress is preserved even without auto-save.
1000x1000 tile world generated deterministically from a seed using
layered Perlin noise. Terrain derived from elevation: mountains,
forests, grasslands, sand, water, with rivers traced downhill from
peaks. ANSI-colored viewport centered on player.
Command system with registry/dispatch, 8-direction movement (n/s/e/w
+ diagonals), look/l, quit/q. Players see arrival/departure messages.
Set connect_maxwait=0.5 on telnetlib3 to avoid the 4s CHARSET
negotiation timeout — MUD clients reject CHARSET immediately via MTTS.
