Migration issues?

Was planning to play around a TWWT gem in Standard (migrated from Affliction),

The Mods were

+(4-5)% to Chaos Resistance per Endurance Charge
Damage Penetrates (5-6)% of Enemy Elemental Resistances
You and nearby Allies have +(15-20)% to Elemental Resistances
(8-12)% increased Area of Effect if you've Killed Recently

I've been scouring my stashes, but can't find it.. is it possible some of these mods would have not made it to Standard?

Thanks.

Check all of your remove-only tabs, and make sure that they aren't hidden.

Was it in your stash or was it equipped on a character?

Migration would not have changed mods on an item.
