Yes PMed Pizpie,
his answer one month ago:
We are investigating this issue. A couple other users have reported the same. I posted about it, and we are looking into a solution now.
Sorry about that mate, if there was a way for me to help I would. However, I am not affiliated with the team so I know as much as you do.
I can only speculate that they are tied up with the release of the new version. Hopefully, the fix for your issue will be included.
That sounds about right, there was some group in China running a lot of nodes, and dumping. I think they are gone now.
While they were messing with HZ the node count spiked to over 4k at one point. That was some serious sell pressure.
