Bug with show_all_map_enable()/disable() and minimap?

[ronzilla]

Hi,
When I run show_all_map_enable(), followed by show_all_map_disable(), some items remain visible on the minimap. In the small map I auto-generated (which is a godsend, by the way), all 8 fish resources and the Bison resource were still visible on the minimap. They weren't visible on the main map, but the minimap still had the little squares representing their locations. There are other resources on the map, but they didn't stay revealed on the minimap.
I noticed that bison and fish were the only resources on the map which generate food; I don't know if that has anything to do with it.

This reproduces it for me, pressing "m" and "n" to enable and disable:

trigger hitM (key_down("m")) {
enable_trigger("hitM");
show_all_map_enable(1);
}

trigger hitN (key_down("n")) {
enable_trigger("hitN");
show_all_map_disable(1);
}

Thanks!
