[1.6.2] Metadata and texture randomly changes???

[CleanPawnege]

So I was making a leaf block and got most of it correct, but for some reason I have trouble with the blockID's(metadata)? So I can place all the 3 different blocks correctly and they render correctly in inventory, but after they have been on the ground for about 5 - 30 seconds they start to randomly change texture to another of the leaf textures? When I middle mouse click(in creative u get the block your looking at in your inventory) and it still gives me the block I placed, but on on the ground it had the wrong texture? This also happens when you place a block on top of any of the leaf textures. And I have tried to use if statement and switch both have the same problem anybody know how to fix?

 

 

Here is a direct link to the correct class in my github directory u can also look at all the other classes if necessary

At line 167 of your block, in updateTick(args) method:

par1World.setBlockMetadataWithNotify(par2, par3, par4, l & -9, 4);

This has a chance of changing your block metadata.
