[SOLVED] New Minecraft world won't load after using mod

[Chixen]

When I tried to load my new mod and create a new world, it loads correctly, but when I join the world, everything is just void, and no commands or chat messages work. This doesn't happen on worlds that have already been loaded. After I save and quit, it just gets suck on the "saving world" screen and can't close without use of the task manager or terminating the program directly. Code is below and console log below that.

package chixen.linemod.core.event;

import chixen.linemod.LineMod;
import net.minecraft.util.math.vector.Vector3d;
import net.minecraftforge.api.distmarker.Dist;
import net.minecraftforge.event.TickEvent.PlayerTickEvent;
import net.minecraftforge.eventbus.api.SubscribeEvent;
import net.minecraftforge.fml.common.Mod;
import net.minecraftforge.fml.common.Mod.EventBusSubscriber.Bus;

@Mod.EventBusSubscriber(modid = LineMod.MOD_ID, bus = Bus.FORGE, value = Dist.CLIENT)
public class EventHandler {
	public static double rotSpeed = 0;
	public static Vector3d lastPos = new Vector3d(5779821.64151,7919321.64151,7987841.64151);
	public static double lineRotation = 0;
	@SubscribeEvent
	public static void onMove(final PlayerTickEvent event) {
		if(lastPos == new Vector3d(5779821.64151,7919321.64151,7987841.64151)) {
			lastPos = event.player.position();
		}
		if(event.player.position().z - lastPos.z != (event.player.position().x - lastPos.x) * Math.tan(lineRotation)) {
			final double cd = Math.cos(lineRotation);
			final double sd = Math.sin(lineRotation);
			final double td = (event.player.position().x - lastPos.x) * cd + (event.player.position().z - lastPos.z) * sd;
			event.player.setPos(td * cd + lastPos.x, event.player.position().y, td * sd + lastPos.z);
		}
		lastPos = event.player.position();
		lineRotation += rotSpeed * Math.PI / 20;
	}
}

EDIT: I got it to work by changing the long random numbers from the lastPos initialization to null, and it worked for some reason. I suspect it had to do with lag, but I got it to work now.
