Well, went back to the castle at the same location, and I am now in a new corridor with a locked door that looks like a set of shutters that won't open or has any discernible switches to unlock it. Going the opposite way I entered simply takes me back out of the castle. Did I break the coding by exiting the castle the first time when I couldn't figure out the puzzle?

 

Edit, disregard things, I didn't realize it wasn't the same exit as normal

Yes, but while I was doing it, one of the rooms suddenly turned dark and the recovery sound effect played, that completely confused me. Not to mention if there was a tile there, I couldn't find it, causing me to leave the area in frustration. Did I possibly break the sequence?

I have absolutely no idea how to do the Vanhaven puzzle regarding Bad Eevee. I know it has something to do with the audio ques and the wall crack growing larger, but I can't discern any pattern.
