Fixes CLIENT-19Q. The issue was that: W3DTreeBuffer::updateVertexBuffer dereferences null mesh pointer after invalid tree type fallback to type 0.

  • Modified W3DTreeBuffer.cpp to skip processing trees if their type is invalid or their associated mesh is a null pointer.
  • This prevents potential null pointer dereferences that could occur if the default type (0) also had a null mesh.
