Translate Ice&Fire

[Ommariuolo]

I have realised an amateur translation of WotN, and all is correct. Now i've proceed translating Ice&Fire, but... The text in eng_* files zipped in loc_ses.kfs work properly for WotN, instead the text in eng_* files zipped in eng_loc_ses_iaf.kfs don't work. It seems that the files eng_* are reading only from ses.kfs.
If I change the files prefix (e.g. from eng_* to fra_*), all work properly until i change island, in this case the game crash.
Any suggestion? (thank you in advance)
