First time I hear about a bug like that. Can you check what's inside the www/pictures/sv_actors folder? There should be one file in there, called aida_test.png.
Ok so I found the folder you were talking about. It is under www/img/sv_actors and I found an aida_test.png and an aida_test(1).png.
Im gonna try deleting one of the copies and see if that resolves anything
It did not
Also is there a discord I can join? I didnt see anything about one when I bought the game
