Destiny: The Taken King Problem With Xur

Alright guys, multi-part question here.

I'm playing the Destiny Legendary Edition on Xbox 360, Hunter Class. (level 40 ,of course)

So, every half-decent Destiny player knows that Xur, the Agent of the Nine, shows up in the tower every Friday Morning, and sells exotics, three of coins, etc, and then leaves Sunday morning.

As I understand it, he sells an exotic armor piece for each class, and then an exotic engram, and a legacy engram. He also sells either an exotic weapon OR an exotic weapon engram, as well as some other stuff.

My problem is this: for the past few weeks (three or four to be specific), he has sold neither an exotic weapon engram nor an exotic weapon. I understand the bug with the Gjallerhorn and empty slot, but I know for a fact that he hasn't (tried to) sell it for three of four straight weeks.

This week, he is supposed to be selling the Icebreaker, an exotic sniper rifle, according to all the websites that track him, and a lot of players say so too. However, he is not selling it for me, nor is he selling an exotic weapon engram. Like I said, the last few weeks, he hasn't sold any exotic weapons or weapon engrams except the SUROS Regime once. I checked my iPhone Destiny companion app, and it doesn't show that he's selling any exotic weapons or weapon engrams either. This is in disagreement with the websites that track him, one of which I'm pretty sure isn't wrong because it (claims) to read what he's selling for the Destiny API or something like that.

Any idea what's wrong?

Also, does it seem like he's repeating items a lot? He's sold the Skyyburner's Annex(hunter), Silver-Plated Ahamkara Grasps(hunter), and Claws of Ahamkara grips (warlock) a lot recently (multiple times each), it seems like he's repeating them a lot.

Does anyone know if any of these are acknowledged or unacknowledged bugs? Is it the fact that I'm playing on Xbox 360? What's wrong? Is anyone else having the same problem(comment if you are for this one don't answer)? Is it just me? Is there a fix or something that I'm doing wrong?

Thanks for any help!

AGAIN, this is not the bug that involves the Gjallerhorn being removed from his inventory
