Amn Lizard Cave not a natural area

[yyj]

This area is a cave, has plants and it's very natural, but the game treats it as an indoor building, can it be changed so that the area gives benefits to Cavestalker for being in a cave?

There's many areas like this on the surface but cannot remember them off the top of my head will be updating this thread if I find more.

After checking, it is natural area. I was able to hips and had my skills increased in there.
