Glitch thingy in shop?

So I was in the shop world and I found my old shop plot, so I went in it and accidently clicked on the chest that was there, because someone else had already bought it. So anyways, I clicked on it and I could open it. First I thought it was lag and it would just kick we out of the chest, so I hit Esc. Then I tried to break a block in the floor and I was allowed to do that, so I placed it back. Could someone please like take away my powers on that shop plot that isn't mine anymore?
