What happened?

I when to buy one more chunk and discovered a rather strange thing, the game says I don't had any chunk claimed so Im able to create another full 10 chunk worth of claims. In the screenshot the blue area is what I always had claimed, the red one is new... not sure how this happened.

maybe someone wants to build his house beside yours？

Both claims are mine, besides if any player builds to near to me it will be war XD I did travel 7k blocks away of spawn to have my quiet place haha

Im assuming this only happend one time, so ill close this.
