Yep I'm exporting the save to XB1 and not going anywhere else in the game on the 360 other than More->Export Save. Other items and affixs that are labeled Patch 2.X appear in the inventory just fine so the save isn't being "cleaned" by the 360. I did however find the video in question. The first video I was watching flashed up a schedule for the future lives streams(summer '16) which is what I was going by. I just discovered when watching another they were all a day off which is why I was thinking the dates weren't corresponding to the video's content. Hopefully I'll be able to figure out what I am missing for legendary gems though I will lay out my steps here:
Create New Item
Assign Gbid as Amulet Tier 17
Under Properties set item's Rarity to Rare
Under Rare Name set to Nimble
Under Mystic I set my desired Affix
Ctr+Insert to fill inventory.
Resign via Horizon and load save on 360, More>Export Save
Import Save on XB1 and note the item(s) name that has desired Affix value, delete all but in the editor
Back in editor change Gbid to desired Legendary Gem
set Affix 1-6 to desired stats
Under Properties change Rare to Legendary, item and legendary level to 70, rank 300
Under Rare name change back to No Prefix
That's all I'm doing and it's not showing up. Hopefully watching through this video will reveal my mistake
Edit: I will add I had this problem last night, prior to the new patch going live this morning
