Everything seems OK now for the most part...
Apparently Valve really fucked this update up because any server (even the ones I don't run) I went into crashed simply by me typing "kill" in console. Thankfully 3 hours after the update hit, the developer of KAC released an emergency update for it to fix the kill bug and a few other commands that Valve broke. So all of our servers are good with that patch in place now.
