Change language errors (and a fix)

[licaon-kter]

Have two languages, eg. EN->FR and EN->ES
Open one, it's ok

Choose the other one only to see:

• title of language is English on titlebar
• Side menu shows language as English with no flag (question mark) and at lvl 1
• Actual words are ok though

Fun fact, changing the device orientation resets the view, bringing havoc in so many Android apps, but here, it actually resets the view and fixes all the bad things.

Hopefully this helps on finding a fix.

I suppose you got this one due to state corruption in #20.
As of now I can at least add English flag.
