XP in AD quest reduced?

[Tampered Knight 8]

A few days ago, reward was 42M XP, but now it's only 36M XP... Is it just me or some glitch?

You probably just lvled above the threshold where the quest gives 100 % exp which should be until 134 atm I think? 135 onwards should result in 75 % exp gained from quest due to 15 lvl difference to the quest. 0.75 x 48 = 36! ?

Quest reward will change as you level up due to the level difference ?
