Nerve damage (neuropathy) can be caused by many conditions, including: 1  Diabetes. High blood sugar levels, common in diabetes, can damage nerves throughout your body. 2  Shingles. Anyone who has had chickenpox is at risk of shingles, a rash of blisters that can be painful or itchy. 3  Chemotherapy.
This is right. The world's usable size is 60,000,000 x 60,000,000, and the nether is exactly the same size. But due to the 1:8 ratio between the two worlds, portals in the nether only work within a square of 7,500,000 x 7,500,000. HUGE. You don't even need to know how big is the nether to be able to build in it.
The Nether Portal was part of the October 31st, 2010 Halloween Update. It consists of a 4X5 frame of Obsidian.The corners of the frame are not required to build the portal and can be mined after creating the portal, and only serve an aesthetic purpose.
