Thanks for posting these instructions! I haven't played Minecraft or BTW for a *long* time now, so I'm pretty rusty on this stuff. :)
One thing though: Did you mean sed s/1\.5\.2/1.5.2-btw/? As is, the dots will match any character.

To my knowledge, they have no use outside the vMC anvil. There is currently no use for them in BTW.

(I'm not a minecraft expert though)

Great! And let me just say, thank you for updating the mod! :)

I remember seeing something about chunks sinking 5 blocks in 1.4.6, is that something I should be worried about?

Really? I guess I didn't think this mod would be so forgiving...

When I mechanically power a hopper with soul sand in it, it won't explode when there are too many souls in it.

Unpowered hoppers still explode.

Edit: Not a bug!

I'm glad mojang is spending their time making fireworks. At least they won't be as bad as something like anvils, and even though they'll be horribly implemented I look forward to having a New Years fireworks display in my world.

And the Command Blocks prove not every idea of theirs is bad.

So I go to the forums to get 3.37... And you've updated again.

Now I'm finnaly going to grow those melon seeds I have!

Wow, you just keep updating this mod over and over...
Now I can finally stop telling mc not to update!
(Still using 1.4.2)
