I noticed flags are missing for the following language packs:
Croatian (Formal Honorifics)
Norwegian (bokmål)
Portuguese preAO
Tatar
The website tries to show the following images but they do not exits:
/assets/images/images/flags/flag_hr-x-vi.gif (can flag_croatia.gif be used?)
/assets/images/images/flags/flag_nb.gif (flag_norway.gif exists)
/assets/images/images/flags/flag_pt_preAO.gif
/assets/images/images/flags/flag_tt.gif
They currently show the generic flag:
/assets/images/images/flags/flag_generic.gif
Perhaps someone can adjust the filenames and add missing flags if needed.
