Weird Output Problem...

Roadhog 4
External Keyboard
External Mouse
Been running the same show file on the same show for 2 days. Tonight, we started experiencing something that I'm having a hard time describing but I'm going to try.
Sitting in a cue (houselights) for over an hour
No one sitting at the console
No other playbacks running
No clock timers running
Fader 1 Cue 1 is up and running
All fixtures in the cuelist drop to 0 intensity.
Output window shows 0 intensity (and view sources says it's being controlled from the Houselight list)
Hit "VIEW CUE" - Values are stored at 100%
If I select the fixtures and hit TOUCH - they come up 0 %
If I hit "assert" or "Go Cue 1" - fixtures come back up.

Comments
Universes 1-4 leaving the console on Artnet
Universe 2 also has a duplicate hardwire output from the console backplane (to architectural system)
I have fixtures parked on in other universes.
This ONLY seems to affect what is on the Houselight fader…(universe 2) - all other parked channels have stayed on each time this has happened.
It happened again…but this time, fader 1 was at full (and chosen)…we had fader 2 up. The drop out ONLY affected the items in fader 1.
After the show tonight, I will zip the show file and send in for testing. I will rebuild the house light list in the morning. Maybe something was corrupted???
Showfile
After the backup, I deleted the entire list and created a new one from scratch. I'll let you know if the problem continues.
I have download the show file and will set this up in the lab.
About how long did this take each time?
How was your network setup?
First time…
Houselight Cue 1 had been running for approximately an hour…
Cam in and they were off….so that's when I started watching and was actually thinking it was a wiring issue (which we found out later it wasn't)
Second scenario…
We had made it through the cuelist (house, house to half, blackout for movie - 90 minutes, credits) and wrapped around back to cue 1….which was active for about 20 minutes when it happened again…
Third time….
Matinee had finished…and we had sat in cue 1 for approximately 2 hours…and that's when I got the photos of the cuelist active, the output window and started grabbing fixtures to see what was going on (and then reported it).
I wanted you to get the file before I made changes. The next day (obviously client was nervous), I ended up deleting list 281 and rebuilding it from scratch and we didn't have any other issues.
DMX/Fixture Net
Physical DMX - using output 2
Artnet 1-8 is being sent to an Elation Node Pro 8 onstage via a gigabit switch in the booth
HogNet
Hognet is being sent to a wireless router for iPad connection, but no connections were active at the time and the router was off.
Also, I shut off OSC, Midi, and everything else prior to scenario 3 to make sure there wasn't something triggering.
I will keep looking at this.
