Nope, same clan, same account, same village, same level, same leader of my old clan I have on Game Center. All same except now in-game name is different. I don't want to call that person out but it happened.
the only way it changes is if supercell change it directly. they mentioned before it only really happens if a username is deemed inappropriate or some rare case like that. what was the guys username previously? it would be good if they all gave us the option to change our name at least once though, they warn new users now when they start that the username is permanent. that wasn't the case when the game first came out.
You guys are idiots, it's already happened. Newbs...probably don't know about the lab glitch back when, so it's also possible to have level 5 troops as a town hall 5. Wait, you're probably gonna respond saying that's not possible either. Hahahaha
Sneakymaori used to frequent our clan, so could have been him.
