Dear hansjakobson,
yes, there is an issue. It happens when you load a rig via MIDI outside of the selected view e. g. Favourites or My Rigs, when you then STORE/REPLACE, the wrong rig might get overwritten. We will fix this in one of our next firmware releases. In the meantime while you are on stage, select view 'All Rigs' and there are no issues.
Sincerely,
Burkhard Dinnies
