Leve Gil Rewards

I like to save my leve's to about 30-40 then use to all at once for a couple hour stint. I noticed today that the gil reward is steadily declining by 2-3 gil now with each 2-3 levequest I complete. I know they lowered the gil you received across the board buI I dropped from 330's gil to 280 gil a level in about 15 leve's. It adds up.

Is this a 2.1 change I missed?

It's actually a random number of gil. I've noticed patterns like that as well but if you keep at it the amounts will go back up and fluctuate.
