The 9th.
At first they recognize the problem and says it applies to everyone, and that they have been told that the dev team is working on a fix.
Then:
"unfortunately til they release the fix we are unable to manualy unlock the set in collections the reason for this is because it may cause conflicts when they do release the fix. As such I request some patience while the development team work on the release and I hope we can get this set unlocked for you shortly"
(the lack of punctuation is theirs)
This was Kreias set, so it was not to expensive, so rather than waiting i just got a new box of the parts i needed from the GTN...
