I thought I saw this map on the EU gameday thread, but I dont see it on the feedback page. Just as a guess, there might have been a bug with the map (some entities that are in Gmod but not Tf2), or maybe it was the custom textures/models I see you used in the map screenshots that ould cause the map to not function properly, and they skipped it. You seem like a new mapper, so I'm going to assume you do not know about packing custom content into your map, and I did see you say you were testing in Gmod, but I dont really know what the problem is.
