Should be fixed now. Let me know if it isn't

[nickwalton]

Nevermind. Is not fixed. Download costs got too expensive so temporarily shutting down bucket access.

Thanks a lot.

Looks like you switched to torrent now? All this works well:

Cloning into 'AIDungeon'... remote: Enumerating objects: 47, done.
...
Downloading AIDungeon2 Model... (this may take a very, very long time)
... We are now starting to download the model. It will take a while to get up to speed. 
DHT errors are normal.
...

Download Complete!

Yes, there was 1 DHT error (Why not catch it and call it something else than a red ERROR?)

And then:

AI Dungeon 2 will save and use your actions and game to continually improve AI
 Dungeon. If you would like to disable this enter 'nosaving' for any action.
 This will also turn off the ability to save games.

Generating story...

You are Andreas, a wizard living in the kingdom of Larion. You have a staff and
 a spellbook. You finish your long journey and finally arrive at the ruin you've
 been looking for. You look around and see that it's not much different than
 when you left it.
As you walk through the ruins, you hear voices behind you. It's another group
 of people who want to know what happened to you

Well done, all good.

Thank you very much!
