This must be an issue on Transifex project.
I was waiting the 100% bar to go down when you update the files for v1.5!

Here you find my language as translated 100%
https://opentranslators.transifex.com/projects/p/opentranslators/language/pt_PT/?project=7119

But when I enter a single file it says:
Remaining 23 36.51%

So I have lots of lines not translated! Probably same goes for the other languages!

- If I enter my language files and hit save the completeness drops from 100% (ok) but then in the project front page it shows 0% done!!

Note: This is an old error revised on Transifex but not solved yet on Opentranslators!
See here: http://support.transifex.com/customer/portal/questions/1224597-wrong-complete-bar-for-some-languages

the localisation project on transifex has the latest lang files - am I missing something in them?

Also updated the language download page. Not sure what happened there...
