it is for sure a bug for consuming questions node! please fix it T.T

I have been playing with the node consuming questions for chayula.

IT DOESN'T WORK.

WELL, IT WORKS IN A VERY WEIRD WAY IF IT WORKS!

It doesn't recover my energy shield as it describes but SOMETIMES! IT WORKS AT SUDDEN!

Like I have 2300 energy shield and after I consume all my energy shield I keep attacking to recover it as the node describes,
but it doesn't recover for 5 mins at all and all of sudden it recovers my 2300 energy shield in zero second.

CAN YOU PLEASE CHECK IT?

FOR YOUR INFO : I HAVE 90 PERCENT MANA LEECH and it works on my mana!
