When I change the Locale: to deand do a reload of the config it switches always back to en.
However it use the German translation anyways, so it's a minor issue.

Build 144

This doesn't happen to me, might have got fixed by some recent changes, let me know if not.

Did no further debug since it kept using the German lang file after a restart...a pm reload did not catch it if I remember correctly.

Anyway it works for me.
