Oh, looks like that's the dynamic map being buggy. It returns y=65 for everything.
Should have realised that. :'S
I think I've sorted the new Nether world. Can you give it a go.
Also, I've just logged in for the first time in ages into the normal world and my inventory is empty. Has this happened before?
I think that was from her chest(s) (nj).
Mine was what I actually had on me.
I think I set up separate inventories between normal and 2012. Might be something to do with that.
This is now out on Xbox. Finally got a friend to try it out and he loves it.
So looks like i'll be playing on consoles only for a while (may be able to get it for pc/mac later).
