You can manually fix that broken link yourself, just run these commands in a terminal:
sudo ln -sf weather-few-clouds-night.png /usr/share/icons/gnome/22x22/status/weather-clouds-night.png gtk-update-icon-cache-3.0 -q /usr/share/icons/gnome gtk-update-icon-cache -q /usr/share/icons/gnome
Then log out and back in, and the icon should display.
