I am Trying to nest Fixtures to a pipe, so that the trim can be controlled with the pipe. It works for a while, but then all of a sudden all the fixtures get removed from the pipes, and put into a "Patch Node". Once it does this, there is no way to recover. I have tried saving show after each pipe, but even reopening the show doesn't put the fixtures back. I put the fixtures in groups, then the groups in the pipe, to no avail. Here is a screen grab of what it is doing, please help.
