You are a mine of information.
Me being me I do keep an eye on what gets paid out and what does not.
I only really take notice of what Steemworld says i will get and i have never noticed any deviation in author reward payouts. My experience so far has been if it says i will get 0.018 SP and 0.018 steem that is what goes into the account.
Am I really mistaken about that ?
And yes i have noticed that the curation rewards are like that frequently
Hmm, since the hardfork the math on the different platforms has varied.
Steemworld will say one thing and steempeak will say something else, beecause of how they deal with the curve ratio.
If the payout was .02 or more, and didn't pay, that is an issue, but I wouldn't know how to address it.
Document it, and if it repeats, I will start asking around.
