Admissions screwed up a shit ton of kids paperwork over the summer do to a turnover in faculty...not saying that was what 100% what happened with Z, but my wife works for UK and she said "the cliques" at UK are likely to blame.
Evidently they've also have had a lot clerical issues due to a crappy software network coupled with incomplete staff work...she's been complaining about their network for years...timing out and losing reports. Their IT department sucks and have screwed her laptop and phone up multiple times.
