I’m not sure when this change happened, but any item I’ve previously bought from the Time Rift vendors is now gone.
I wanted to buy the Fel-Ridden Divider to mail to my Warlock for his Felguard. However, I’ve already learned this appearance, and now I can’t buy it anymore? So is this just forever unavailable for my Warlock?
I don’t have a warlock, so pardon the basic reply, but if your account has learned an appearance, you should be able to “equip” that appearance via transmog on any class / faction that is allowed to normally equip that. I’m fairly certain you’re aware of this, but I’m also replying to help bump this and to provide info for anyone else potentially reading this.
However, I’m not sure about the fel guard point, because, like I mentioned, I don’t Lock.
It’s an axe, and Warlocks can use a glyph to make their Felguard equip an item that’s in their inventory. So, he’s unable to use the appearance and I can’t use the glyph because I don’t have the item in my bags.
Oh wow. Well that’s cool. Now I see the issue.
Buy yourself a cheapie two handed weapon (axe, hammer, sword, whatever) and transmog it into the Fel-Ridden Divider. Throw that in your bag and it SHOULD work with the glyph. Maybe.
Edit: I’m an IDIOT.
You can’t mog the axe because you can’t HOLD it.
If annything else, this is certainly a clever - and better than mine - response.
Is there anyway to mog a BoA weapon and give it to the lock?
Yup, there’s the issue. 
Blizzard had NO reason to remove items from the vendor just because they’ve already been purchased.
Now that’s interesting, maybe a heirloom weapon? Have a warrior alt “summon” it, mog it, try to send it to the warlock? I’ve never tried sending heirlooms, but I suspect they’re probably BoP once summoned.
Yeah I think so too. Or, maybe even when mogged they soulbind.
There has to be a loophole, there just has to be. I’m representing an entire class that made a deal with the devil and figured they could get the better end of it, a stubborn weapon should be no problem!
Maybe see if Blizzard can make it so it is any weapon you have the look of, I.E. any you can mog
Shame there isn’t another skin like that as BoE in game.
That was an interesting idea. I tried it - mogged an heirloom, mailed it to the Warlock, and it lost its transmog skin. So, this didn’t work either.
Heres the thing though. The item was just a cosmetic. And not an actual usable thing. It wasn’t equippable by anyone. It was just a cosmetic. You could only “equip it” to your cosmetic bank.
Yep, just tried this and came back to report it myself.
Sorry Rev. There isn’t even a decent alternative drop model, the closest is one that RARELY drops from certain bosses back in Legion zone assaults. Even then, it’s grey and purple.
Dang. That really sucks.
According to a comment on WoWhead, it still worked for the warlock glyph if you kept the item in your backpack.
At this point I’d say open a ticket. It’s a long shot, but there’s no way in-game to make it work, as far as I can tell.
But that’s not the point. Had I bought the item on a Warlock, I could’ve kept it in my bags and used the glyph. But since I’ve learned the appearance, I can’t buy the item at all anymore, making it unusable with my Felguard. This should not be the case.
But you didnt have an actual item. Unless youve done this before and have that knowledge, as far as I know you do not have a weapon in your inventory. You have a cosmetic.
It still is a weapon. It’s a two-handed axe. You just can’t equip it, but you CAN use it with the Glyph of Felguard.
Edit: And yes, it’s been confirmed by other Warlocks this does work, even tho it’s a cosmetic weapon.
Yeah I made a thread about this that nobody saw. Warlocks really need those weapons to be purchasable.
