I get this now with my MN:
Warning: Your masternode version (120100) is behind the official version (120102). This is from DASHcentral.
I am running 12.1 so do I need to upgrade again. I just updated last week...??
and go through the update procedure and reset my time and loose rewards etc.
I don't run any on dashcentral. Do you run your remote node (vps) there? It should be taken care of by them. You don't have to start-alias your mn from local. It's simple update and you won't lose your rewards.
No, I run my own on a VPS, I just use Dashcentral to monitor the MN. So, is it just a matter of replacing the dashd on the server? what about sentinel?
