Yeah, so, I'm the other person, and the top stalactite is falling on the lower stalagmite. When I enter the world for that 1 second I can see the top stalactite impaled into the ground, and then it kicks me. Maybe that's why? I tried doing a kill command, /kill @e[type=entity.minecraft.falling_block], a teleport to the void command, /tp @e[type=falling_block] 20, -64, 350, and some other stuff I outlined in another post.
