The weirdest round I've ever experienced, possible bad ghost spawning?

I was playing Willow Street and the ghost room was in the living room. I began to try to gather evidence but didn't get anything, only that the temperature seemed to approach very close to 0, so I assume it was freezing temps. According to the screen in the van the ghost was very active, but I didn't see any interactions while inside the house: no movement of doors, no light switches (meaning no possible way to check UV) and no interactions with the fusebox. I even put a motion sensor to see where the ghost was in the room and it didn't activated a single time.

Because I thought the interactions were happening when I was away from the room and I seemed to have freezing temps as evidence I went for Shade, it was a Myling. I know that the ghost can just not do anything, but at the end of the round I saw it made 16 interactions?? Could the Myling have spawned in a corner where it couldn't move and made it impossible to give evidence?? Because that's the only explanation I can give to the interactions.
