On the first day, I saw boxes and decor on Skull Island, but as of last night and today, it's all gone. Has it migrated to other islands? If not, this is a very disappointing holiday being as it's so short and Halloween is still 12 days off.
I have the feeling it has something to do with how bug fixes are scheduled. That is to say, they take the last database, put the bug fixes into that, then set it up so the next update replaces the databased. This happens probably days before the bug fix actually occurs.
Then the database is updated to allow the Halloween or Christmas celebrations to begin.
Then the bug fix database is overlaid on top of the celebratory database and the decorations go away.
See, the problem is they need the database with the celebrations available a week before it is available.
What needs to happen, I think, is the celebratory process needs to be put on both the regular database and the bugfix database at the same time. That would solve the problem.
