I made the sample project and just tested it. It works as intended there, leading me to believe the issue is another one of my plugins but there are many, and I already mentioned the ones that specifically work with regions afaik. Would it help to list my plugins? Or would it be better to send a project with all of them running at once, so the issue is replicated? I just thought that it was bad to send whole projects full of people's plugins even with a credit list.
I will try turning some off and on to see if I can locate the conflict. In the meantime here are the plugins.
