Is anyone else seeing this in their #Minecraft Bedrock worlds on PC? I've seen it a few times so far.

These are appearing in random locations, but all within visual range of my original spawn point.

The first time I saw one, I reloaded the world and it was gone. Second time, I got close to it and the blocks would disappear after being hit. But THIS one... is apparently made of real blocks.

Can anyone help me figure out what's going on and if it can be fixed? @Minecraft @MojangSupport
