So I have this issue whereby if I load a world with my Tile Entity (crate), it will crash the game and give this error:

Caused by: java.lang.RuntimeException: class cout.sngtech.beneathMod.tileentities.TileEntityOakCrate is missing a mapping! This is a bug! at net.minecraft.tileentity.TileEntity.writeInternal(TileEntity.java:72) ~[?:?] at net.minecraft.tileentity.TileEntity.write(TileEntity.java:66) ~[?:?] at cout.sngtech.beneathMod.tileentities.TileEntityCrate.write(TileEntityCrate.java:81) ~[?:?] at cout.sngtech.beneathMod.tileentities.TileEntityCrate.getUpdateTag(TileEntityCrate.java:95) ~[?:?] at net.minecraft.network.play.server.SPacketChunkData.<init>(SPacketChunkData.java:47) ~[?:?] at net.minecraft.server.management.PlayerChunkMapEntry.sendToPlayer(PlayerChunkMapEntry.java:146) ~[?:?] at net.minecraft.server.management.PlayerChunkMapEntry.addPlayer(PlayerChunkMapEntry.java:63) ~[?:?] at net.minecraft.server.management.PlayerChunkMap.addPlayer(PlayerChunkMap.java:224) ~[?:?] at net.minecraft.server.management.PlayerList.preparePlayer(PlayerList.java:261) ~[?:?] at net.minecraft.server.management.PlayerList.playerLoggedIn(PlayerList.java:331) ~[?:?] at net.minecraft.server.management.PlayerList.initializeConnectionToPlayer(PlayerList.java:162) ~[?:?] at net.minecraft.network.NetHandlerLoginServer.tryAcceptPlayer(NetHandlerLoginServer.java:114) ~[?:?] at net.minecraft.network.NetHandlerLoginServer.tick(NetHandlerLoginServer.java:65) ~[?:?] at net.minecraft.network.NetworkManager.tick(NetworkManager.java:257) ~[?:?] at net.minecraft.network.NetworkSystem.tick(NetworkSystem.java:151) ~[?:?]

 

Also loading a new world then placing the crate down then exiting and going back to the world that crashed me doesn't crash anymore for some weird reason until i restart the game.

 

This is my github: https://github.com/SNGTech/Beneath-Mod/tree/master/src/main/java/cout/sngtech/beneathMod

 

Help would be greatly appreciated! Thanks

You haven't registered your tile entity.

@ObjectHolder(Main.MODID)
public class TileEntityInit 
{
	//Storage
	public static final TileEntityType<?> OAK_CRATE = null;
	public static final TileEntityType<?> SPRUCE_CRATE = null;
	public static final TileEntityType<?> BIRCH_CRATE = null;
	public static final TileEntityType<?> JUNGLE_CRATE = null;
	public static final TileEntityType<?> ACACIA_CRATE = null;
	public static final TileEntityType<?> DARK_OAK_CRATE = null;
	
	@Mod.EventBusSubscriber(bus=Mod.EventBusSubscriber.Bus.MOD)
	public static class RegistryEvents
	{
		@SubscribeEvent
		public static void registerTileEntities(final RegistryEvent.Register<TileEntityType<?>> e)
		{
			e.getRegistry().registerAll
			(
				//Storage
				TileEntityType.Builder.create(TileEntityOakCrate::new).build(null).setRegistryName(Main.MODID, "oak_crate"),
				TileEntityType.Builder.create(TileEntitySpruceCrate::new).build(null).setRegistryName(Main.MODID, "spruce_crate"),
				TileEntityType.Builder.create(TileEntityBirchCrate::new).build(null).setRegistryName(Main.MODID, "birch_crate"),
				TileEntityType.Builder.create(TileEntityJungleCrate::new).build(null).setRegistryName(Main.MODID, "jungle_crate"),
				TileEntityType.Builder.create(TileEntityAcaciaCrate::new).build(null).setRegistryName(Main.MODID, "acacia_crate"),
				TileEntityType.Builder.create(TileEntityDarkOakCrate::new).build(null).setRegistryName(Main.MODID, "dark_oak_crate")
			);
			
			Main.logger.debug("Registered Tile Entities");
		}
	}
}

This is not how to register tile entities in 1.13.2 Forge?

How then do I go about doing that?

TileEntityType.register("oak_crate", Builder.create(TileEntityOakCrate::new)).setRegistryName(Main.MODID, "oak_crate"),
				TileEntityType.register("spruce_crate", Builder.create(TileEntitySpruceCrate::new)).setRegistryName(Main.MODID, "spruce_crate"),
				TileEntityType.register("birch_crate", Builder.create(TileEntityBirchCrate::new)).setRegistryName(Main.MODID, "birch_crate"),
				TileEntityType.register("jungle_crate", Builder.create(TileEntityJungleCrate::new)).setRegistryName(Main.MODID, "jungle_crate"),
				TileEntityType.register("acacia_crate", Builder.create(TileEntityAcaciaCrate::new)).setRegistryName(Main.MODID, "acacia_crate"),
				TileEntityType.register("dark_oak_crate", Builder.create(TileEntityDarkOakCrate::new)).setRegistryName(Main.MODID, "dark_oak_crate")

ive tried doing this but i get a registry error (so obviously thats not how to register them)
