Your grass and wildflowers are sculpties.  When you upgraded your viewer, the LOD setting was probably dropped down to its default setting, which makes it difficult to see them properly.  Open your Advanced menu (CTRL + Alt + D), go to Debug Settings, and type in RenderVolumeLODFactor.  In the window that opens, raise the number to something between 3 and 4.  That should do it.
