Nah, it's actually in how you use setmap.

If you setmap yadda, yadda, 0,0; people will appear in level 0, 0 - usually a black square on peoples' maps.

If you setmap yadda, yadda, 9.5, 13; people will appear halfway through the 9th level from the left, at the top of the 13th level from the top. Or maybe it autocenters, but I think I'm doing this right.

The reason they appear in the blackspace anyway is because they don't have a map coordinate - these people are inside a building or on a different map, yet are not excluded from viewing on this map. In theory the solution is setmap yadda, yadda, 255, 255; then they'll be so far off the map you can't see them - but nobody seems to want to do it that way, and there's the problem of what if they make a map that big (I think Classic's Endless Freaking Ocean map is nearing that...)
