I actually have some thoughts about emerald tools.
If they ever did make an emerald tier, my opinion is that it is similar to the gold tier so that it discourages players to make the tools and use them as the villagers' currency.
If they make them strong than diamonds (which I doubt they would) my opinion on that would be to use emerald blocks or emerald ingots made by two or three emeralds. Just some thing to make it more expensive so people emerald farming would have to use more than 35 emeralds, which they could easily obtain, to make every tool and armor piece.
This is just my opinion. anyone can share their input on my opinion.
P.S. I do not believe they will make emerald tools.
Define Cute (choose 1): A) Creepers Aerbunnies C) Herobrine. If you chose A): You appeal to destruction and to stereotypes. If you chose B): You are a perfectly normal person, and enjoy the Aether Mod. If you chose C): Please leave the planet now before you set off a nuclear warhead--no one enjoys mass murders, however nice they might seem to you.
I found 3 bugs:
-Doors can't be opened when holding something
-You can't leave a line open when writing in a book.
-Pistons and sand became very buggy: my redstone door (which pushes sand into the air to close and drops it to open) is acting very strange and has problems opening properly (door gap is 2x2).
Can somebody test those things out en see if he has the same problems? (a lot of people are having the first one I can see in the comment)
