German tree bug

[jankor]

Hey, yesterday about 20 of my german tree lessons that have been completed before turned into non finished locked lessons.

We're aware of the issue and working on getting this fixed. Sorry! Expect a fix very soon. Thanks for the report.

hello dear, after 5 years the problem still exists.
the lesson "people 2" have been completed without ever touching it. can you please fix it?

[kristinemc]

This should be fixed now. Thanks again for your patience!

Thank you, just a small note. Seems the tree have been recovered to the state I had during the tree update. But the lessons I have finished after the tree update are still shown as unfinished.
