ETC Gio Live/Blind don't match

Hey folks!

So we had a funny problem during our IDR last night. We were in Live, all our values were stored, but when we looked in Blind the values did not match. We were definitely looking at the correct cue stacks and nothing was manual. It only really affected one channel that we noticed - everything else looked right. Has anyone experienced anything like this before? We haven't upgraded to 2.9 yet, working on a Gio. 

This may or may not relevant, but this morning when I attempted to power on the Puck with the multi-console power on command on the board, it didn't work. It has worked fine before this.

Are we haunted?

Thanks all!
