In return to your bad luck it has happened here in northwest iowa as well. My dad has shot two 130+ class bucks this year and we have not found either...My friend also has shot a buck this year with no luck finding it...And these guys are not bad shots we will not even go deer hunting untill we can put four out of five arrows in a beer can at 40 yards, granted there is the adrenaline factor to figure in but that has never been a problem before. ..with a combined hunting experience of 40+ years...I don't know what it is but i hope it is about to end...
