Sorry you are still having problems. Just to confirm this is happening with a completely fresh install and fresh play through? Just checking off everything I can think of here, I assume you are in the afternoon, after classes for the day too?
Holly is a side quest, so you should be able to still complete the game without activating her quest. Are you able to progress from an older save before you activated her quest line?
If it's a fresh file, we'll have to take a look at your save to see what's happened. I'll have Kal look into it, if you have access to patreon contact me there or on twitter so we can take a look at your save.
Once again, I'm sorry you've encountered this bug. We will do our best to get this sorted out for you.
