I find that some of my junction nodes think they are bigger than they should be, so if they are not widely separated from adjacent nodes then they show the ! warning of overlapping nodes.
If I move the function node (or the junction) across a bit then it is ok. Is this a known issue?
I raised the upstream issue, but it appears 'upstream' has been abandoned and no fix is forth coming. We need to figure out a way around the issue... which is less than ideal.
Sorry Nick. I am getting too old. I did remember that there had been a problem but I didn't remember that I had rolled back as a workaround. I have removed that code and it is ok now.
