please load new map already
It is already uploaded, however the ladder bot's will still use the old one for some time, coz it still has bugs, and needs some testing.
If you wanna play on it to try out, use the non-ladder bot.
You can do this with type in the chat:
/w lagabuse.com .map dota v6.83c
than /w lagabuse.com .gopub gamename
Have fun. If you find some bugs, you can write it here, it would be a good thing.
