This might have something to do with one of the oldest persistent bugs we've dealt with on the platform. That being, when you're zoomed out to see the outside border of the canvas, it will add more rows of grid units to the bottom or to the right side of the canvas. So technically, when zoomed out on a 25 x 25 page, you are suddenly seeing a 35 x 25 page as the bottom of the page extends to the bottom of the screen. The additional grid units don't actually exist, but you can drag content over onto it when it's displayed, which effectively moves the object off the page entirely and prevents you from accessing it again without having to pull the resize tricks you've had to do previously to get it back on the page again. The current work-around is using a background image that fills your exact page size. So when you zoom out, it's obvious when you're looking at parts of the page that are basically "badlands" territory when it flows past the backdrop image. Not an ideal work-around, but it'll help you avoid getting your objects lost while we try to fix that issue. Edit: That being said, we've done quite a lot to nail this sucker of an issue down. Are you having this issue with every campaign you use?
