Its still happening, the node that joins says "Transition master
unknown", while all of the other nodes who the master is, then the
master gets kicked out. Then a new master is selected, all of the nodes
seem to know who the master is, but refuse to act on it. After a while,
the new master is kicked out and the process restarts. I guess its
related to the changes with the timestamps to prevent master desync, I
dont see any other recent change that could have caused it.
