Translations I have made to the Vector extension in December are yet not deployed in the live wiki.
Changes to other message groups (such as Core or Abusefilter) are up to date and I can spot no problem in those groups.
When WMF MW version was 1.16 I was told the reason Extension Updater could not update Vector was because of a trunk move of this extension in relation to its branch counterpart.
I wonder if this is still the same issue.
Link above points to r78274.
Fixed by clearing and rebuilding the LU cache. There seemed to be some issues with applying the trunk move you mentioned on the cluster.
