I have advagg module enabled v 8.x-3.4, and lang_dropdown module v 8.x-2.0-beta1. When I enable aggregation, js file (modules/contrib/lang_dropdown/js/lang_dropdown.js) from land_dropdown module is not included into aggregated js file for logged in users (for anonymous users works fine).
I tried setting preprocess to false in lang_dropdown library, 

js:
    js/lang_dropdown.js: {preprocess: false}

and it works fine then, but of course you cannot hack contrib module.

I cannot see any error in the logs either.

Any suggestions why this js file is missing?

preprocess must be TRUE to allow JS to go into aggregates. I'll take a look and see if I can see what the issue is.

With a simple installation of admin_menu, advagg, minimal locale modules and lang_dropdown (beta 2). I see it getting included. Is it still happening if you clear your caches?
