Hi,
When using Multiverse, and this might be a multiverse update or just how it deals with maintaining the spectrum, it will not restore a light when/if it is repatched. The light needs to be flashed to zero for it to restore to it's previous setting. This turns out to be pretty annoying on set if a technician has to ask for a light to be flashed every time power needs to be rerouted.
There needs to be some option to restore on power up or that it checks the signal again. My suspicion is that MV only sends when values change to preserve spectrum bandwidth and that is the real issue.
