They are working on that issue if I'm reading this correctly, according to this alioneye tweet-

That particular tweet was Jason H trying to explain why Section 114 was empty for the Western Carolina game (visitors not required to return unused comps), but that does not appear to be correct.
However, Derek Neal then joined the twitter conversation saying use of 114 for opponent's fans was just a one-time deal per the contract of the B1G-ACC Challenge. He went on to say Krush was supposed to be in 114 Saturday, but no one told the ushers, and he promised it would be fixed.
Behind the bench--Section 13--if they get the entire section, has just 46 seats for opponents' fans (if I count correctly). Again, that location is standard operating procedure for all college games, and if the opponent wants/needs more seats, they are usually in nosebleed territory.
