I seem to be automatically getting the wand to progress right off the bat. I found this out when I started a game the other day, but didn't get a wand so I just left the page but when I went to go play another game yesterday(With the 200 diamonds from the advent, thanks so much!), but found that rather than resetting the game it allowed me to continue until the end. I thought, well maybe it's a bug, but I'm still going to play my other game. And it allowed me to go through to the end again.

Frost tokens get you to level 1, but you can advance as high as long as you get the wand.
Gold, you automatically can play the first two stages. And same as the first, if you get the wand to go to the third.
Diamonds you get to automatically go all the way thru.

I hoped this helped.

That seems a little op, but that's nice I guess, makes sense since it costs so many diamonds and it'd suck to pay 500 diamonds for a bunch of baking ingredients I'd just sell for a few thousand gold. Thanks!

If you read the announcement Krin made about the Winter Wonderland it's all explained in there - best to read all the pings from Admins really as they often have interesting and important info in them - Krin is keeping a close eye on things to make sure it doesn't end up oversaturating the market because it's overpowered etc, I had similar concerns to you and voiced them and he was happy to listen so I wouldn't worry about that :)
