Yup, and to spare the poor devs some time I checked the code, and I think this was the problem :
(file crew_and_followers.util.js on line 987 in the lastest public patch)
By meddling with the page, I found that this expression cannot cover all the file names for her busts (for exemple I found a file called ardia_sub_balls.Adjatha.webp) or can link to an inexistent file (for exemple ardia_horse.Adjatha.webp doesn't exist but is requested when she has a horse cock and is clothed).
So I believe you either need to change this line or to change the name of Ardia's bust files.
