Thanks, I'm (sorta) glad it wasn't just me.
When I went back to build 40, the sequence lower nodes were still bad, and I was thinking I would have to rebuild the entire sequence again, but then I finally found that once I clicked on the first effect in a node row, all the colors came back on for all the rest of the effects within that row. So I just had to do that on each row to get the lower nodes to start working again.
I've seen this before where I've found nodes were 'colorless' and clicking on them (or sometimes just rendering again) would return the colors on all the nodes. I am trying to move as much as possible out of the nodes up to the top level but not everything I had previously done have I been able to find an existing effect that would do the same thing, but I'm trying.
Thanks again for checking it.
