So I recently started having this problem after re-installing the crowd render addon after not using it for a while. I get a ghost render node that shows up that has the same name as the PC I am using blender on. If I click the "-" button it goes away for a second and then comes right back, if I try to connect to it it connects and then another one appears. This makes it a lot more difficult for me to sync and render, any ideas on how to fix it?
