This happened to me again at a gig this week and I was able to recreate the problem. I was on preset 49, selected a new preset using the Preset + button, should've gone to preset 42 which was programmed in my setlist, instead jumped to preset 177 in the Axe III. Once there, I've found no way to get back without power cycling the mastermind. I'm on the latest firmware and tried the suggestions above, "Direct Send PC/CC" and "Send Redundant PC's". Also tried the CC #0 suggestion to get back down a bank with no luck. Completely baffled.
