When layering in creating maps, i.e. using the "To Front" and "To Back" options, whenever the campaign is restarted, many items are put behind the larger tiles. For example, when I'm trying to create a village and placing houses on top of large grass tiles, everything lays out just fine. When I come back to the map later to continue editing, my houses are often underneath the grass. As a result I have to go through my map and send each large tile "To Back" before I bring my players into the new scene/
