HIVE IS NOT WORKING.

I had the same issues, but I didn't focus on them. Both maps and campaigns were created in one of three editors – RoE, AB, or SoD. The new editor can open old maps, but the old editor cannot open new ones. And in Platinum (also known as SoD), old maps and campaigns play perfectly well, so no one would likely bother redoing them in the new editor. This is probably where the problems stem from.
