The Lighting Controller

We had one month off between shows and our last performance was fine, no issues. This past weekend, nothing worked as programmed. All lights matched the addressing in the software and all lights powered up and were functional, but nothing was even close to what I had programmed. Many of the multi-LED lights illuminated only 2 or 3 LEDs and some were really bright and some were really dim. I brought home 3 moving head lights and have been trying to figure out what has gone wrong. At first, they worked fine. So I tried shutting it down and restarting, and then it wasn't working. So I created a test scene with the 3 lights and they worked fine. So I went back to the main light show and it has been working fine. I have 2 more shows this year - the next coming up in 4 days and I'm hoping someone can help. I'm really a noob at this, but I'm stumped as it has all worked fine for the last 2 years.

I'm running version 9.2.23 (yes, I just found out there is a new version) I''m using a macbook air running macOS Catalina 10.15.7. All lights are in 1 universe, all lights are Chauvet, all DMX addresses on fixtures match the programming. Tried different cables - no improvement. Sending over the show file after I post.

Not easy to check standalone data without your lighting equipment.

Please try to do that:
1. use the option "erase existing standalone data"
2. reload the standalone data
And tell us the result.
