This is not my work
I just realised the mod was not available anymore.

I acknowledged that there's another mod that does almost the same thing and was uploaded around the same time, both based on the same original mod. That said, this one offers more translations into other languages and doesn't cause any issues with the French version of the game. Therefore, I don't see any reason to remove this mod, at least until the issue with the other mod is resolved.

This mod was made by (-Gesicht-)
With the version of BLT2.0 he stopped working - And (rewdiees) updated it under BLT 2.0
He let those instructions to fix the original mod from Gesicht

How to fix it yourself

1. Go to the folder Custom Fov -> menus -> text file "modoptions"
2. In the line -> parent_menu_id ":" lua_mod_options_menu -> write so ->" parent_menu_id ":" blt_options

But he also added fix from (Music Piano Plays) (i don't have more information on that).

Have fun
