Where the problem is:

 

 

[glow=red,2,300]String var2 = (String)classToNameMap.get(this.getClass());

[/glow]

        if (var2 == null)

        {

            throw new RuntimeException(this.getClass() + " is missing a mapping! This is a bug!");

        }

        else

        {

            par1NBTTagCompound.setString("id", var2);

            par1NBTTagCompound.setInteger("x", this.xCoord);

            par1NBTTagCompound.setInteger("y", this.yCoord);

            par1NBTTagCompound.setInteger("z", this.zCoord);

        }

 

 

My Tile Entity is missing the class mapping, how do I fix this?

its because in you main mod file you should use (for all types of tile entities )

 

 

 

GameRegistry.registerTileEntity

[/spoler]

You get this erro because your tile entity its not registred so minecraft dosent writes it to nbt if u relog into your world the block (or anithing else) will desapear.

I already had that, please tell me what to change in it

 

GameRegistry.registerTileEntity(TileEntityKoriumMiniChest.class, "containerKoriumMiniChest");

GameRegistry.registerTileEntity(TileEntityKoriumMiniChest.class, "containerKoriumMiniChest");

public class TileEntityExpBank

 

something wrong huh?

oh... herp derp thanks
