As I hinted here, this version of the RLV contains a new debug setting named "RestrainedLoveHeadMouselookRenderRigged" to help you decide whether your head rigged attachments (those attached to "skull", "chin" etc) should render or not while you are in mouselook. The default is "not".
That way if you are having trouble seeing your body because for some reason your mesh body is attached to the head (or your mesh catsuit, or any mesh outfit that covers your body) and you don't want to or can't attach it elsewhere, you can set this debug setting to "true" and it will render again while in mouselook.
To change a debug setting, especially a "RestrainedLove" one, simply open the Advanced menu (press Ctrl Alt D if you don't see it), go to "Debug settings" near the bottom.
Type "Restr" then press Enter, this will select the "RestrainedLove" debug setting.
Then click on the down arrow to open the list and choose the debug setting you wish to change. Most of them do not require a restart and "RestrainedLoveHeadMouselookRenderRigged" does not either.
Once set to TRUE, your rigged head attachments will show while in mouselook like they did before RLV 2.9.25.
