On the mobile theme, the list of posts show's the latest replying user's avatar, not the OP's avatar

An option to show OP avatar vs latest reply is important for a large community. In desktop view it is apparent who posted the OP from the topics page. Currently in mobile, only the user with the last reply shows up. I am currently choosing to not display avatars at all in mobile view because @charleswalter 's script no longer appears to work. Thanks.
