1- I got rid of <TileMinimap> and tried it, no change. Switched to getting rid of <ImgMinimap:Cityl> and putting in <TileMinimap>, and I now have a white square, so progress, but I need the tiled minimap, and not just what is passable/impassible. I had a map like that before, and given some things I got going on, the map didn't make any sense.
2- It LOOKS set up to me, but I am not sure-- I have tried referencing the help document, and I can't make heads or tails of it. (Note: it was a misunderstanding of the document that caused me to put both of the tags in the map notes)
