I've been killed by chickens before so... yeah. I tried to place the blocks from different angles, they kept smashing. I closed down Minecraft, but when I tried again they kept smashing, the particles that come out when you smash things actually came out when it happened. I've had run-ins with Herobrine before but they weren't anything like this, so this is kind of weirder than you'd think. If anyone knows what happened please tell me.
The Chunk lagging wasn't the main point, it was no damage when I hit the ravine floor. As for posting Screenshots, I know how to take them, but my computer won't let me post them. The chunk lagging led me into a cave, and not just on the surface. Which is weird for me because I usually end up back on the surface.
