I made the site from the PDA mission my base. "Engineer's Lunch-box" or some such. I can't seem to make it a navpoint. I went to Registry, selected "Show Private" and there it is "Engineer's Snap-tin" or some such. Told it to add a navpoint. Fine.. it says.. I can do that for you.. and shows me a little arrow right next to "Engineer's Tool-box" or some such. But can I see it on my map? No. Can I see it on my mini-map? No. Can I see it on my HUD? No. So I have to look for the place where I put all my stuff. Eventually I catch sight of "Engineer's Pencil Box" or some such. I am almost inside before it decides to show on my map or mini-map. That won't do. D.
How far away from the base were you when you noticed it wouldn't appear ? This appears to be just because of the mapdistance parameter in the playfield.yaml setup for this POI. I'll check if much can be done for this particular scenario.
