I have the strangest thing happening and I don't understand it at all.
I have a hero viewing camera setup to show all my hero's and the selection screen. I've been using this camera for years. I add new heros, place them on the screen using the preview function on the camera, preview it then publish my map.
I recently added a new hero, placed it on the appropriate location and tested it. Every time I test it it looks fine, (I run the SC2 Test document).
Now when I publish the map and run the game, the hero's location is always moving, either up or down, (mostly down so you can't see it). Every time you start the game, the hero is in a different location. It is the most bizarre thing I've ever seen and makes absolutely no sense to me. This doesn't happen if you run test document, only if the map is published.
