Artnet Bug?

Seems I have come across a bug that when we log into our files (Hog 4, 2.2.0) -- it seems the console does not always begin to output art net. I have put a packet viewer on the network and confirmed that when we power down the console and cold start into a show (any show) art net does not start. You log out and log back into the show it and immediately starts outputting art net. Any other shows we load or change to after the console has been left on, will then output art net immediately upon show load.

Anyone else seen this issue?
