Seble had mentioned that 2.0 recruiting effort would not carry-over into 3.0. However, 3.0 effort (on a non-qualifier or other recruit that goes JuCo) would carry-over into the next 3.0 season.
Best guess...those recruits have disappeared entirely. Less likely, they still exist as JuCos, but your effort has vanished. I don't *think* there is another possibility.
