You can't put doodads into WMOs that way due to how the client culls. Either add them as WMO doodad sets (unsure if there are tools), or spawn them server side.The texture you used for ground appears to be missing a _s.blp equivalent. This is needed for shading and is automatically loaded, ending up in crappygreentexture.blp if not found. Either switch this texture to a different one, where the second texture exists, or add such a texture (the alpha layer has to indicate where and how much the ground will reflect sunlight. As a quick hack, you could make it completely transparent, so that it does not reflect anything. Otherwise it should look like the original texture.).
