The essence drop rate

[Tippertwo]

Hasn't seem to drop.

I've gotten more energy essences from WT4 than I know what to do with
(my inventory is near full of energy)

Yeah, it's fixed now. But when they made the 12/22/15 update the essence drop rate dropped.
I did the wt4 when they made that update, and I got one essence per run :/ But it's fixed now and it's working great! ^^
