No big deal for me, since there are no achievement prizes tied to any stage:

Krypt Konqueror ★ Navigate the ever-shifting passages of the Crypts and find your way to the treasure room. 1 74/5 10 25 50

So, I've Conquered the Crypts 74 times, rank on Conquerer and on Cumulative. As you can see above I am at 74/5 stuck at the second instance, when it should be at the last 74/50.

I have found several hundred Frankenpie Slices, the count for Frankenpie Collector is at 2/3

I have no idea, in what way Secret Passage Expert (6/10) and Into the Depths (7/9 - no, not the Borg) differ from each other, the count certainly should be higher with my scores.

Crypt Cartographer (steps 50 100 500 1000) has a rectangle around it - meaning earned them all?

Ice Fields - all steps start at 0 for me I don't know, how many Frozen Cookies and Buckets of Polar Water I have found in my life - my current possesion are 99. So, it can't be I started at zero with the Icefields...

Cookie Monster You have an uncanny ability to find frozen baked goods in the snow. 4/5 10 25

Polar Scavenger There's treasure buried under all that snow, and you're the one finding it. 1 1/5 11

Frostbitten The cold doesn't bother you anymore. Mostly because you can't feel anything. 10 19/25 50 100

P.S. - off the first page I stumbled across this:

Polar Ice Field Navigator ★ Brave the frozen tundra and return with a Bucket of Polar Water.

1 5 10 10/25

I think achievements are generally in a state of havock ever since kissing started, right? Reminder: Kiss a User Prize for the last 2 stages is the very same title, there is nothing like title squared ;-)

Those achievements aren't counying for me either. I've found 3 frozen cookies and it says my count is 1. I also can't get passed the first page or two lol
