(Python)

In kata descrition there is a note:
1<n<10^6
1<k<10

I have some failing tests and this is the output of one of them:
"81514610699888 should equal 5094663168743"
Those numbers are much bigger than 10^6
Log output should be more descriptive like: for n=some value (k=val2) should equal: val3

I think there's still problem with this kata.
In the description it's said:
Just for extra clarification, an item can never have its quality increase above 50, however "Sulfuras" is a legendary item and as such its quality is 80 and it never alters.

And here's a part of log from random tests:
Starting items in the store are {Very Aged Brie, 2, 60}, {Potion of Weak Love, 6, 58} and 5 days passed
Checking item 1: Very Aged Brie
Test Passed
Not the expected quality value: 50 should equal 60

According to the description only sulfuras can have quality >50. Besides - 5 days passed condition and quality raised by 2 each day.. where it is said?
Please, verify requirements vs tests.
