I'm doing a hard look, at all my facility files, for Keroman, looking for what might be causing the problem. Also comparing my files, against stock facility files. Can't get into the blasted SKDs right now, since Word won't work.

(What does it take, to attach pics?)

The groundplane 'model' for Keroman, is partly raised, making for a seawall, on the water side. Part of it sits over/mating with the stock scenery. It also extends farther out, to make the ground surface, for the bunkers to be located on.
Okay...here's my problem. Sometimes, the groundplane flickers, off and on. Also happens from high altitude. Kinda rolls in and out, from watching it.

Any ideas what I need to look at?
