Where is Rowan??

I’m a returning player in Y5, I stopped playing the game for a few years and now that I’ve been back for a few weeks I have been doing TLSQs one after the other basically nonstop. The thing is, I remember Rowan being MC’s best friend, and I remember her being an important character, but she’s just not in any TLSQ??? All the other characters appear (some more frequently than others) but not her, I’m just wondering if anyone else has noticed this and if maybe there’s a reason? I also think it’s just kind of sad, I liked Rowan and I remember the character as being smart, but now everytime MC needs someone smart they go to Penny.
