Ok so when you go into and out of the nether it takes half a heart from you. On top of that when you go in it constantly transports you back and forth from the overworld to the nether. And since you take damage, it kills you.
By back and forth, I mean you go in then you load for a second then you go back and then that keeps happening. This is really frustrating my friends and I. It would be great if you could fix it within the next snapshot. Thanks
