It sounds like Sona was still considered to be in the office when she shouldn't have been, blocking the other characters from performing their attack actions.
Did Sona attack you before that happened? Was there a light flicker?
I Feel like I remember Being attacked by Invertness Right before the Glitch happened, Sona was at the Door though when it happened
Alright, I think I have a fix for it. It'll be in the next update when I release it.
