So i was making slabs and this one i have is called a "Crystal Slab" and it's see through kinda like a crystal so when i have been trying to do it, It keeps crashing like if i load into a world place it on the ground it has a see through effect all the way past bedrock, And if i place a slab on top of it, The game crashes, But if i place the top one first and the bottom one it acts normal, And btw when the game crashes when you load back in it's like if you were in spec mode but every block is gone and the game ends up crashing, If you know the problem please let me know because now i'm past my time for releasing alpha 2.0 for my mod lol.






Heres the class for BlockSlabBase


 

public abstract class BlockSlabBase extends BlockSlab
{
    Block half;
    public static final PropertyEnum<Variant> VARIANT = PropertyEnum.<Variant>create("variant", Variant.class);
    
    public BlockSlabBase(String name, Material material, BlockSlab half) 
    {
        super(material);
        setUnlocalizedName(name);
        setRegistryName(name);
        setCreativeTab(CreativeTabs.BUILDING_BLOCKS);
        this.useNeighborBrightness = !this.isDouble();
        
        IBlockState state = this.blockState.getBaseState().withProperty(VARIANT, Variant.DEFAULT);
        if(!this.isDouble()) state = state.withProperty(HALF, EnumBlockHalf.BOTTOM);
        this.half = half;
        ModBlocks.BLOCKS.add(this);
    }
    
    
    
    @SideOnly(Side.CLIENT)
    public BlockRenderLayer getBlockLayer()
    {
        return BlockRenderLayer.TRANSLUCENT; }
@Override
        public boolean isOpaqueCube(IBlockState state) {
            return false;
}

@SideOnly(Side.CLIENT)
   @Override
   public boolean shouldSideBeRendered(IBlockState blockState, IBlockAccess blockAccess, BlockPos pos, EnumFacing side)
   {
       IBlockState iblockstate = blockAccess.getBlockState(pos.offset(side));
       Block block = iblockstate.getBlock();

    
     
           if (blockState != iblockstate)
           {
               return true;
           }

           if (block == this)
           {
               return false;
           }
           return false;
       

      
   }

    @Override
    public Item getItemDropped(IBlockState state, Random rand, int fortune) 
    {
        return Item.getItemFromBlock(half);
    }
    
    @Override
    public ItemStack getItem(World worldIn, BlockPos pos, IBlockState state) 
    {
        return new ItemStack(half);
    }
    
    @Override
    public IBlockState getStateFromMeta(int meta) 
    {
        IBlockState state = this.blockState.getBaseState().withProperty(VARIANT, Variant.DEFAULT);
        if(!this.isDouble()) state = state.withProperty(HALF, ((meta&8) != 0) ? EnumBlockHalf.TOP : EnumBlockHalf.BOTTOM);
        return state;
    }
    
    @Override
    public int getMetaFromState(IBlockState state) 
    {
        int meta = 0;
        if(!this.isDouble() && state.getValue(HALF) == EnumBlockHalf.TOP) meta |= 8;
        return meta;
    }
    
    @Override
    protected BlockStateContainer createBlockState() 
    {
        if(!this.isDouble()) return new BlockStateContainer(this, new IProperty[] {VARIANT, HALF});
        else return new BlockStateContainer(this, new IProperty[] {VARIANT});
    }
    
    @Override
    public String getUnlocalizedName(int meta) 
    {
        return super.getUnlocalizedName();
    }
    
    @Override
    public IProperty<?> getVariantProperty() 
    {
        return VARIANT;
    }
    
    @Override
    public Comparable<?> getTypeForItem(ItemStack stack) 
    {
        return Variant.DEFAULT;
    }
    
    public static enum Variant implements IStringSerializable
    {
        DEFAULT;

        @Override
        public String getName() 
        {
            return "default";
        }
        
    }
}

And if you take out the see through code

 it's normal and acts normal, But it's not see through like it should be.

And if i place a slab on top of it, The game crashes

I don't see a crash report.

Cannot get property PropertyEnum{name=half, clazz=class net.minecraft.block.BlockSlab$EnumBlockHalf, values=[top, bottom]} as it does not exist in BlockStateContainer{block=supersurvival:crystal_slab_double, properties=[variant]}

You're trying to get a HALF (top, bottom) value for your double slab block which does not have that property.

 

Also, you didn't include the entire error so I don't know where this is happening.

O sorry, Here is the pastebin of the startup and logging in and when it crashes https://pastebin.com/enySRiwx 

1. java.lang.IllegalArgumentException: Cannot get property PropertyEnum{name=half, clazz=class net.minecraft.block.BlockSlab$EnumBlockHalf, values=[top, bottom]} as it does not exist in BlockStateContainer{block=supersurvival:crystal_slab_double, properties=[variant]}
2.     at net.minecraft.block.state.BlockStateContainer$StateImplementation.getValue(BlockStateContainer.java:204)
3.     at net.minecraft.block.BlockSlab.doesSideBlockRendering(BlockSlab.java:107)

You haven't overridden that method, and its doing something that's causing a conflict with your block. You'll have to figure out what to do yourself.
