While I was in the end, i wanted to get the Dragon egg because I had just built a new ender portal transportation system to it, and had a piston and a redstone block at the moment. I go to the end, and start building around the dragon egg with ice, because that was what was readily available in my inventory. I start building, and my game suddenly crashes. I check the crash notes, and it said Tessellating Liquid in World. I realized, that when the ice melted it had just crashed, and it has now actively locked up my world, because whenever I start playing, it just crashes.
Please fix this, I've played 20+ hours at least on it.
