i think you r right, this can be the only possible reason of delay from LVO, otherwise if they continue with the pace like this i dont think they will be able to clear fsw 2013 applications in 2-3 years
I juast want to learn one thing, when we say LVO doing BG CHECK, SO LOOKING to NDVO speed at which thy are issuing visas, so how did they complete BG checks? and on the other hand we say that files r picked randomly for BG check
now when you reapply it will be considered a new application for which you need valid ielts, as your ielts expired in december 2013 so you have to take ielts again
