I was seeing plenty of deer Bow Season. Come 6 day Firearm they were extinct , till finaly the last day. Pheasant season was open the weeks prior and seemed to turn the deer nocturnal. Maybe the same is happening to you. Since you say you are hunting next to cut corn, maybe other hunters are getting there first. Just a thought. It happened in my spot it could happen in others. Thank God their not stocking anymore.
