i already checked its nowhere to be found

hi, in legacy league i enchanted a voll's vision helmet with "Lightning Strike pierces 3 additional Targets" and corrupted it to a malachai's vision helmet.
i put it into my stash, but after the patch i checked my "remove only stash" and the enchant was gone.. or the whole item..
in the patch notes was something about a change of lightning strike pierce, but just checked that this enchant still exist
its long time ago, but wonder if its possible to get the item back somehow ?
it was in legacy league before it gets a little nerf to energy shield
