Why Christmas Box RNG is badly coded: Statistics say something is funky

eekeeboo: I'm glad to see there's been an explanation on math and how chance/randomness works, this has saved me a lot of work and effort to explain!    Thank-you guys for being constructive and on-topic and keeping things civil.    As highlighted it's not about badly coded RNG, but the fact that each box will have a loot table to draw from with chances, if you're super lucky you could get tier 5 from every box, it's all about how chance works!
