[Freeciv-Dev] Bug: flags in unit help

[David Pfitzner <dwp@xxxxxxxxxxxxxx>]

Can anyone work out why the race flag no longer shows up behind the
unit icons in the help dialog for units?  I think it broke when the
diagonal roads patch went in, but I can't see what's wrong.
Flags work ok in other respects (the main map etc), but the
relevant function create_overlay_unit() is only used in helpdlg.c
