Sorry for the lack of follow-up for so long. I was holding off until I had the time to manually look into each person's trees. I definitely should have said something sooner though!

For everyone here:

• First, are you sure you didn't remove all the ornaments from your tree at the end of past holidays? The snapshot we have is from the very end of Luminaire, so if you had removed the ornaments after the season, they will show up blank.
• If you are certain that you didn't, could you please let me know the specific year(s) that seem to be missing for you? I will look in the database to verify that it's not an issue with rendering, or at least let you know if the data is just not there for whatever reason.
