方块状态导致的奇怪问题

@Override getMetaFromState跟createBlockState后在第一次执行tile.setEventActivation结束时会产生一个新的block_1Entity对象并且tile指向的对象会消失，最终结果是tile.setEventActivation就像从来没有被执行过一样，但如果在让tile.setEventActivation重新执行一次他又可以正常的运行了 不会出现对象被吞掉的情况，这让我非常不理解。
同样是tile.setEventActivation(true);第一次执行完EventActivation仍然是false而第二次之后就可以正常的根据参数改变了

public class block_1 extends Block
{
    public static final PropertyBool ACTIVATION = PropertyBool.create("activation");

    public block_1(){
        super(Material.ROCK, MapColor.LIGHT_BLUE);
        this.setDefaultState(this.blockState.getBaseState().withProperty(ACTIVATION, false));
    }

    public static class block_1Entity extends TileEntity{
        public block_1Entity(){}
        private boolean event_activation;
        public void setEventActivation(boolean bool){
            this.event_activation = bool;
            IBlockState newState = world.getBlockState(this.pos).withProperty(ACTIVATION, bool);
            world.setBlockState(pos,newState);
        }
    }

    @Override
    public boolean onBlockActivated(World world, BlockPos pos, IBlockState state, EntityPlayer player, EnumHand hand, EnumFacing facing, float hitX, float hitY, float hitZ) {

        if(world.isRemote){return true;}

        block_1.block_1Entity tile = (block_1.block_1Entity)world.getTileEntity(pos);

        tile.setEventActivation(true);

        return true;
    }

    @Override
    public BlockStateContainer createBlockState() {
        return new BlockStateContainer(this,ACTIVATION);
    }

    @Override
    public int getMetaFromState(IBlockState state){
        return 0;
    }

    @Override
    public boolean hasTileEntity(IBlockState state) {
        return true;
    }

    @Override
    public TileEntity createTileEntity(World world, IBlockState state) {
        return new block_1Entity();
    }
}

问题解决了，setBlockState在改变BlockState的同时会改变游戏内Block的实例 需要重新getTileEntity
