Irregularity in nifty f&o

Its strange. Spot down and futures up and just a few strikes away puts are in deep discounts. Ex 24800 pe trading at 360 whereas it should be around 440. And this scenario is also happening for monthly expiry options also

options(excluding expiry day) follow future, future is not following CAS closing, so yesterdays 75 point CAS jump is irrelevant, ignore cas closing then it will make sense.
