Masternodes have already started getting paid.
No, if you look at the in-wallet block explorer and compare it to any of the PIVX clones that actually work, you'll see that the entire 18.00000000 SPDZ is going to a single address for each block. The 18 SPDZ is NOT split into separate UTXO's for the reward split between masternode and miner. Have a look at the explorer within the wallet of PIVX or any working clone and you'll see how it SHOULD look.
