I have a second house and a hideout which I would like to be able to teleport to from my main house. So I placed a couple of command blocks side by side (see pic 1). The one on the left leads to my hideout, while the one on the right to my second house.

The one on the left has been there for a while, and I have used it several times. Works fine. It was when I put the one on the right when things started getting confused.

Second pic shows the code I used for the left one, and third pic shows the code for the right one.

But when I triggered them, the one that was supposed to take me to my house took me to my hideout instead, and vice versa.

I got rid of the right one, re-placed it on the roof of my house, and re-coded it. It worked fine.

Strangely enough, when I put it back next to the other command block, nothing triggered. I got rid of the one that I placed on my roof and tried it again. Didn't work.

Side note: Google Play says my version of MCPE is 1.17.0.02, but for some reason it doesn't exist on this website.
