Strange Cue Drop and IFCB drop

3.6.1. 2xHog4 full 2x DP8000, PRG Switch to PRG fiber to S400 system.
350 Movers
After 4 days of very successful hard days of programing two strange things happened.
First the Rig would drop, this was totally random but would freak me right out, I would bounce through the cue list and it would not happen then out of no where the rig would drop ?
Second thing
After the show was over there was about 50 people on stage and I had the wash on a IFCB handle when I moved the Handel slow to pull do the wash it instantly dropped to 0% ?
The consoles come out of the truck Monday then I can send the show file if needed.
