Not sure how much mining power you have in that contract, but sometimes it falls below the min payout amount and they bank it until it hits the appropriate level. Also, if you are having it paid out in STEEM then with the price increase, that might account for the lag ..

If you check out the MY ORDERS section you'll see how much has been accumulating ..
