I posted this on the official forums as well.
Quote We have all of the MapCore entries and the build that it was generated on (0.1.2). We'll be judging them from that point, where they were submitted in the build that they were submitted for. As for the fallout of the CTF-TitanPass update, we'd like to verify that what people are seeing as broken in their pak files is actually broken in the editor/after a re-cook as well. If that still doesn't fix things for you it would help us if you could provide more details about broken/missing items.
Otherwise as we've mentioned before our content is often subject to change as levels are being iterated on. We generally try to avoid changing things in such a way that they cause any fallout but as a rule of thumb it is always wise to at least copy out your own master material if you wish to differ from the "Official Look" (tm) of that set. It is definitely not our goal to sabotage anybody's hard work and we care to get you guys fixed up
If we can identify that some assets are missing somehow we can release them separately to get this addressed. Again, we're sorry that this issue has occurred.
