Comment (by pcfreak30):

 So I spent a good few hours debugging this to find this bug! The bottom
 line is you can unload translations, but you cant add them back unless
 they are the core ones. the
 {{{_load_textdomain_just_in_time}}} function needs {{{|| isset(
 $l10n_unloaded[ $domain ] )}}}
 removed. I was doing this as part of a multisite plugin activation routine
 with rewrite rules since the language switcher would NOT switch languages
 properly.

 Here is a gist of some of the code in my (public) plugin that I had to use
 to get my use case fully working:

 I think there is a design flaw in this that needs to be looked at again.

 Thanks!
