Hello from Greece. I am facing the same problems as many other users on this page, but also one more: I get a message in Greek saying that the translation I have built is based on an old version of the original article, and that the content has changed and I may want to consider starting the translation again. NOT the case! The last edit on the English article (Keio Plaza Hotel) was on 11 November, and I started yesterday, i.e. 30 November! When I mark the issue (and also the e.g. "90% untranslated" notifications) as resolved, I get the 400 error. I missed my contribution to Asian month because of this. Please help me at least salvage the work i have done...
