I noticed that the nebulas in Omicron Theta didn't show up on the system map, even after you've visited them. I thought this was strange, because I couldn't find any other examples of nebulas/fields/clouds that didn't show on the map after being visited. I decided to see if it was obvious what was different about these nebulas in the ew04.ini file. It didn't take long to see that the zone sections for the Napo, Orinoco, and Amarus Nebulas had a "property_flags = 16384" entry, but the nebulas in other systems had a value of 32768. I changed the entries for the 3 nebula zones to the more-common value, and now the nebulas are visible on the map! I don't know if this is a "bug" or not, but I can't figure out why this would be done intentionally... anyway, I definitely prefer being able to see them on there.

Sorry if this is old news, but I didn't see any related posts.
