Day 11 when Callum is behind me after I ring the bell (when Rosalinde drives away) instead of going up the stairs to the house he just... phases through the stairs and the door opens by itself and then closes. He can't be seen inside, either. So yea. He just clipped through everything instead of going up.
Oh weird! That used to work. I’ll look into it.
I played through a second time. That time I met him over near the carport and he walked to the stairs and then up them normally. Might have been a one-off bug. I'm not sure, I haven't done a third play, yet.
