Haven’t gotten payout in a long time

I’m using the Minermore pool, and just mining on an RX 480 whenever I’m sleeping or at school. I suddenly stopped receiving payouts (I have the payout threshold to 2 RVN) on about March 30th. I used to get at least one payout per day, sometimes multiple. So I checked my dashboard and everything seems to be in order, my wallet address is correct, it shows one worker, and nothing has really changed with mining or my pool settings. Has the mining difficulty gone up? My hash rate is consistent at 11MH/S.
