While visiting a neighbor, i forgot where I was and I went into main, then my profile and clicked on 'use gift' and it put me in my neighbors catalog, not mine. You can actually change their catalog orders. It happens with all my neighbors too, not just this particular one. I am playing on an iPad. This is a BIG breach. Of course, I didn't do anything untoward, but some other person may. This needs to be looked into ASAP.
