So in one of my survival worlds I made a stone generator. It creates stone and pushes it forward using a piston. Using my diamond pick, sometimes the particles for a broken block would instead show the "Update" block. How do I know? The texture looks like dirt with clearly green pixels on it, distinct from a grass block. You can tell it is bits of text. After doing my research, I have not found anyone else with this problem. In fact, most Minecraft websites say that this block impossible to even be seen without jailbreaking your phone, hacking, or using inventory editors. They also say that this block shows when there is something coming in the next update (and you somehow have it). All I am doing is mining stone from a stone generator with an enchanted pickaxe. I highly doubt that the enchantments matter, but I will include them anyway just because.

Name: Ice Breaker (Originally was a pickaxe I made to break ice)
Enchantments: Silk Touch I, Efficiency II, Unbreaking II

The following pictures are of an "Update" block, if you have never seen one. The other is a picture I took of the particles (A clip of it is too big)

One more thing I forgot to mention is that I don't know what really causes this. It might not be breaking the stone, it could be something else. That is why the title has a question mark in it.
