Wow! I did not give due attention to this message.
At least at the moment, it seems like this error is not repeated.
Thank you very much for your help and speed.

P.S.
I mistakenly at one time deleted the localization file for freak_forertress 2 by confusing it with another file.
freak_fortress_2.phrases.txt
and
ff2_boss_selection.txt
