Fu*k, After having nearly one and 1/2 days of event playtime - event monsters timer return to original design (24 min- common, 48 min - rare, 1hr36min - Epic, 3hr 18min - legendary) from equality (24 min).
AND here I was planning to make use of this rare chance to farm Mythic girl Matilda to level 10.
IF IT IS NOT AN INTENDED CHANGE, THEN KINDLY GIVE SOME NOTIFICATION IN ADVANCE AND TIME FRAME FOR CHANGE PLEASE.
