Hero Keys not dropping?

Well i just recently bought some magic boxes things and the Hero keys are not dropping. Did they stop dropping?

As of Yesterday I still saw them dropping. Can't you buy them at the Elluel potion NPC as well?

I saw one drop from onna' dem guardian things in time temple.

You can't buy them unless i missed them and I guess its just my luck or the mobs im hunting?

Where are you hunting?

They probably don't drop in "world tour" areas, including Masteria (Haunted Mansion, Aliens) and Singapore (MP3).
They should drop at LHC but the kill rate there is lower than at places where you kill mobs in one or two hits, so you might go an hour without seeing a single key drop.

And what level are you?

And what level are you?

That doesn't matter to event drops.

If it helps i am 136

That doesn't matter to event drops.

Maple Leaves and the purple presents stop dropping. Depends on the event really.

And I haven't seen the keys today, either.

So they stopped dropping? Awww pooh

Taken from here under the part about the music boxes,

*Update 6/8: There's been a shortage of Hero's Keys, but there will be another shipment coming through by Tuesday, June 12, so hang tight! Once in, the keys will continue dropping until midnight on June 14.

Oh wow thanks
