Sam's Simple Theme

The avatars and usernames of last poster are missing from Suggested topics list when using this theme:

Steps to reproduce:

  1. Open Sam's personal "minimal" topic list design
  2. Notice the (all/some/none) missing info. Change to private tab/different browser if necessary.

Is there an easy way to fix this? Should I open a #bug #feature or #support topic? This affects every site that uses some variation of the minimal theme that I know of.
