RPG Roller confusion

No matter what I did for the past few days I hadn't been able to pass this challenge. I even directly copied and pasted solutions other people had said worked (I know, but I needed a correct model to see what was going on) and even those weren't working. So, this morning I started again fresh only to find the code below wasn't working either, until in a fit of frustration I clicked the "check work" button 3 times without changing anything and it worked. So I'm a little confused as to what is happening. Is my code actually correct or did I find a bug in the challenge.

dice.py
import random


class Die:
    def __init__(self, sides=2):
        if sides < 2:
            raise ValueError("Can't have fewer than two sides")
        self.sides = sides
        self.value = random.randint(1, sides)

    def __int__(self):
        return self.value

    def __add__(self, other):
        return int(self) + other

    def __radd__(self, other):
        return self + other

class D20(Die):
    def __init__(self):
        super().__init__(sides = 20)
hands.py
from dice import D20

class Hand(list):
    @property
    def total(self):
        return sum(self)

    def __init__(self,size = 0, die_type= D20):
        super().__init__()
        for _ in range(size):
            self.append(die_type())
    @classmethod 
    def roll(cls, size):
        return cls(size, die_type = D20)

If you can get both a pass and a fail from the same code, that sure sounds like a bug.

You might want to report this to the Support staff.

I must have done something before I checked it the last time, because it works every time now. Thanks though, Steven.
