I looked into the SFC3 mission map.cpp, and .h files and found that creating the SFC3 map seems to be handled differently, no editing, rather that API use routines to add objects at particular map coordinates-- unfortunately not a help in my question about SFCOP although it looks fun and I will be tackling that soon, so the question still stands about OP, anyone know how to add the Ion Storms (which symbol to use for small or large Ion Storms). As always, thanks in advance!
