[2023 Day 7] Part 2 poorly specified (mander.xyz)

The instructions for part 2 are missing info about how to handle the Four Of A Kind and a joker case. Wasted quite some time because I assumed that the remaining joker would remain unused, but turns out it turns your deck into Five Of A Kind.

Did everybody else just expect this?

For part 2, the only thing that I missed at first was the JJJJJ edge case. My approach was:

count the amount of jokers
remove them from the hand
count the rest
add the amount of jokers to the biggest set in the hand

Last step fails if there are no other cards left after you remove the jokers...
