We had something interesting happen tonight that I thought I'd share. While programming, my designer called for channel "x" out. On his RVI, the channel value still showed 60%. The show is being programmed with an Ion as the master and an Eos as the client. The Eos (where programming was taking place) registered the change.
Additional changes in intensity to the channel in question did not clear out the stuck channel. Ultimately exiting out to the shell and re-syncing cleared out the issue.
It wasn't much of a problem since it only related to one channel on the RVI, but I found it interesting.
