I feel your pain Mesh, applied almost 1 year ago and still says received, got employer nomination approval June 2017 and C/O called my MA and said we just need 2 more docs and should be all good.
Since then nothing, its extremely hard and frustrating having your life on hold, can't buy a house always- doubting about whether it will eventually get approved, but I guess in your case I would chase them up. I try not to focus on it too much or I get annoyed about having to wait again.
Live and hope and will keep you all in my thoughts for good news very soon!
