so i had a question about this as well, simply because it's the only thing i can think of that would be keeping me from progressing. i've unlocked flare, sevros, and alek, and all of them are absolutely maxed out on affection and have all their preferred settings, but i haven't levelled up to get another character yet. the two reasonings i could think of was that i was missing something with one of them, or that i just had to speed through the days until something changes. 

if there isn't anything i can do about sevros' lighting, what else can i do to get reputation points and level up? 

also, small recommendation. to make it more official that you don't have to worry about sevros' lights, maybe after asking him about the lighting it can give the "correct lighting" pop-up? and change how the conversation replay shows up in the "ask" category, because all the rest of them say things like "diet still good" while the lighting one just says "lighting conversation", so it kind of makes it seems like i haven't completed that section yet
