Okay, maybe I've added to the confusion here. I kinda put two issues together, which for me seemed as one issue but it doesn't appear that that is the case universally.
Lemme break it down.
I bought 2 character slots from the GW Store. On one I created a Ritualist, on the other I created a Paragon during the preview event. I have never been able to get the Factions pre-order special weapons for my Ritualist. I can get them on my other six characters but not this one.
I was able to get the Broken Toy and follow through and get my Mini Grey Giant during the Nightfall preview event.
When I started playing the same character I created during the preview event last night, this time with a CE key added and already accessed to get the mini pet, I was unable to unlock any bonus items (including the Broken Toy for the Mini Grey) with my paragon.
Suspecting that I had the same problem happening that I have been happening with my Ritualist I deleted my Paragon and started it up again in a new Nightfall char. slot. After I did that I typed /bonusitems and got the whole shebang, Factions pre-order weapons, Nightfall pre-order weapons and the Broken Toy.
Now I'm not sure if this is the cause for everyone else not being able to get the Broken Toy (for the first or second time) but I do know that that is what worked for me.
Clear as mud?
Jayna.
