Now I "caught it". For some reason P3D just stopped working today. I was having trouble with Plan-G and later found out the plan I had made was corrupted and it would not let P3D load, the "startup scenario" which I have "on" wouldn't come up. The P3D screen came up, then just disappeared, no P3D at all.
So been reinstalling all day, finally got P3D working again. All is well except the Tongass Area ... and nothing but trees at Wrangell (no water) and screwed up water levels at Sitka ... so I think the problem is with Tongass X. I reinstalled it (using Estonia Migration), and have the same problem. Mesh is at 5. I look at the FSAddon link and signed up for the forum, but didn't get "authorized" yet ... so I don't know what Holger's text there says. If it works, it is something we should put on our site I think. If anybody has it, shoot it at me. I'm totally out of ideas. The Misty's Place area is fine ... so it is something unique in Tongass.
