And a very rare chance to aconteser this drop texture bug when we are mining for breaking rock or any other block, "the block came without texture" this bug already happened to me a few times but unfortunately could not take print. I think it has a 10% chance of happening this bug texture.
The drop of the block is with that pink and black texture "bug" texture but when he got in the ground it is normal with standard texture.
