I literally only made an account in the forum to see if anyone else had this happen to them. D: Mystery sign popped up by itself. There was only two others in the world and I was near the house the whole time and didn't see anyone enter. Here's the screencap. Also, I'm on peaceful in creative mode. I deleted this one and another appeared a few minutes later. THIS IS NOT A TROLL! I seriously want to know why this is happening!!!
Sorry but unless this sort of thing happens in my own world where I can see it first hand, which it never has in the 3 years I've been playing Minecraft, I call BS.
You can call BS, but it's happened twice. The second time I was near the house and everyone one else was doing their own thing. And I don't like to troll unless it's funny. This is not funny. This is weird. I'm also a pretty rational person. If I thought it was someone else trying to troll me, I wouldn't even bother trying to figure it out.
Hahahah, oh you. XD I wanted to make it out of something different though! :3 I just wish people would believe me/tell me what this stuff is! I thought it might be some kind of Halloween themed Easter egg. XD
And I'm probably alone in having this happen. Ahaha
Yeah, I'm not sure. It's just weird. I was skeptical the first time, but I know one of my friends doesn't have the spelling skills or grammatical prowess to make that. And the second one appeared after the other friend and I came back to the house together.
Also, I deleted that one and a new one appeared a few minutes later.
