Alaron Is.: S23 Torriage Wood North has a floating tree at the center of the map, about 2/3 of the way north.
The terrain and the textures look great. The grass looks great. (I'd actually like to know who built it, because it looks like L3DT was used, and I'm interested in learning the texturing process from L3DT imports using YATT in the NWN2 toolset.)
However, it wouldn't hurt to go through these areas, hide everything in the toolset except for trees, turn off tree leaves, and just view the trunks, and move around fixing heights until they aren't 2 meters above the terrain.
Alaron Is.: S24 Rillifanes Run Int
specifically at Weirdwood El'dan of Rillifane merchant shop. The returns bin is inside of a post, and so part of it is on non-walkable area, so the entire return bin can not be accessed by players. The bin needs to be nudged slightly so that it is in fully walkable and fully baked area in order to be used.
Also, the shadows are too deep in here, and prevent you from seeing the merchant's face. He's right next to my character in the screenshot and he looks almost invisible.
