So i texted about my problem earlier in mod comments, and here i want do some clarifications:

So, the problem itself - i do not have "Mods" brochure at desk, i only have "Bombs" and "Menu" brochures, BUT i still can choose to play "Missions (Translated Modules)" at "Bombs" brochure, so it looks like mod is installed and working, kind of. (But i can't get to Mods” => “Mod Settings Folder” => “TranslatedModules-settings.txt” to change the language).

Let me describe every dialog window i see after the game start:
1) "Mods and External Content Warning" with 2 buttons (disable/enable mods), ofc i pressed "enable mods";
2) "Mod Manager Menu" with 3 more buttons (Browse Steam Workshop; Manage Installed Mods; Close Mod Manager), here i go into "Manage Installed Mods" to make sure that checkmark at mod is on, and yes it is on;
3) "Mods modules are now active" screen which allows you to open manual folder (i already got manual, so i don't need it), also this screen explains that if you need to access this menu again you can use "Mods" brochure at the desk, so i press the "Continue" button.
Thats it, now im at desk, with only 2 brochures (Bombs and Menu).

P.S. I restared the game like 10 times after installing mods, reinstalled mod and game itself, nothing helps, i don't even know what can cause this problems
