Question about the map "Empire of the World".

These aren't bugs; they're player errors. Bugs are errors within the game itself, where the developer intended one thing, but something else happens in the game. I've written everything clearly enough. Play maps from the RoE, AB, and SoD versions in SoD ("Complete Collection" or "The Shadow of Death"). Play maps from the WoG version in WoG. Play maps from the HotA version in HotA. Purely strategic maps can be played in any version (if in WoG, you can also "WoG-ify" them at the start). The map version is displayed on the website where you download it, in the map editor, and in the game itself in the list of maps and saves (with an icon). I'm attaching a screenshot showing this clearly. "Appeals" is SoD, "Crimson and Clover" is RoE, "Twins" is AB. For WoG maps, it will be an eye; for HotA maps, it will be a Horn. You can download maps from this or this website, where everything is well-organized, and screenshots, descriptions, and other information are provided.
