LocalisationUpdate not working?

This typo has been fixed half a year ago, but the change is still not live on hu.wikipedia (eventually, the local MW page had to be changed). Shouldn't the LocalisationUpdate extension sync such changes every few days?

As far as I know LU is working for Wikimedia, although I cannot verify that. Yes, it runs every day for Wikimedia.

Another example: MediaWiki:Flaggedrevs-hidereviewed/hu has been translated two months ago, but it is still showing up in English (screenshot, link)

In FlaggedRevisions the file have moved location. This is why there is no synchronisation possible between the trunk branch and 1.18wmf1 at the moment. I would advise you to open a bug report for flagged revisions on that in bugzilla:.

We have bug open for this at bugzilla:33122. Problem still not resolved as of r107515 running on Wed Dec 28 23:54:10 UTC 2011 on Wikimedia.
