This doesnt happen only in the nether, It happened to me a few times that creepers/ zombies/ skeletons spawned in between bamboos on the overworld
Actually is pretty normal for a rabbit to not drop meat sometimes, it has a chance of droping it, unlike pigs or cows that aways drop at least 1 meat
You need to open in a beta 1.8 or 1.8.1 version first to open the alpha word in 1.7, anyways is normal to happen those chunck errors when opening a old world in a newer version,hope that this helped
Playing since 2011 and not knowing that, what a shame for me, anyway Thx
Sure Dag Hef, but also with cobblestone and stone
But isn't is supposed to smelt stone things (cobblestone and stone ) too?
This happened with me too
and this crafting table is looking kinda weird
