so far i can tell these three either dont pay MN fees or pay less then required or run unknown masternode versions as of late :
XxDotRpSDzgyAkx3jHkLZD8YYZRwbcjmmA : getting unpaid blocks with unknown masternode version
XkETHbymbZgkpjHG3f4Ad8osWg3XkPta5L : paying 20% with masternode version 0.11.1.19+
coinminepl : paying the required 37.5% with unknown masternode version
my pool (coinmine.pl) has upgraded wallet to latest version - it happens from time to time that masternode payment is not to the latest version...
feeleep
sorry feeleep, i updated my post as i noticed that the records sometimes show unknown masternode version and other times v0.11.1.19+
but in both cases they do show yr paying the full 37.5%
it may be that drk.mn recognize it wrongly... anyway - I am open to help if I can
thanks .. i'm starting to think its most likely a case of drk.mn not updated yet and giving you ''unknown'' masternode version when yr updated before
that site itself updated. something like that ..
or its just a glitch in the matrix

edit : i did a check with the unknown masternode version and it turns out its running version 0.11.1.21, maybe thats why drk.mn is naming it unknown masternode version
