The list is completely up to date (regarding the format it's in), with every prize box we've ever seen listed with all contents - cept Companion. Scroll down to the bottom to understand more about the list - repeats of boxes don't get multiple rows. They just get numbers next to their contents.

Caketastrophe didn't have a prize box the first year - it was an energy package like the first time we saw dragon wings. The box itself is called "Anniversary Prize Box" (IDK why they name things the way they do sometimes...Katastrophe? IDK!!?!?). The second box (for the third event) had a different name, with a year after it -"Anniversary Prize Box 2014" so it gets its own row. This part of the table organization is based entirely on the name of the item as seen in-game, helping keeping things clear...and allowing people to search for things on the Auction House and so on.

We don't put the percentages in the list because they are subject to change with multiple instances of boxes and that's a hassle to update. We decided not to include percentages a while ago in another thread, I'll try to find it - but it's old. Maybe it was even in-game, hmm...

I wouldn't be willing to put the percentages in. They give us percentages for the buy-boxes, but not lockboxes, and it's best for players to go to "official" pages when things concern their monies - that is, the pages made by Thalia, linked to in the list. There's other important monies information on those pages too. That being said, if someone wants to put the percentages in, feel free, but just make sure they're correct and all that. I just want to encourage people to read official GM posts, it's good to direct people to such things.

I kind of wonder what would happen right now if someone opened a polar prize box that they had since 2013...

If more clarity is desired regarding multiple instances of prizeboxes, I can throw together a cute calendar?
