I have upgraded to 1.1.0-RC2 and the problem still occurs. As far as I can tell the problem occurs no matter what pedalboard is used. When I turn on the mod there is initially an empty pedalboard. The problem occurs even if I click "New Pedalboard" to replace the empty one. I am also prompted if I want to save this pedalboard, even though it is empty. Also the problem occurs if I add some pedals.
As I said, my work-around is to open a new tab and re-connect to the mod. In the new tab the "Loading pedalboard" icon spins for a few seconds and then I get an emply pedalboard.
I have attempted to share a pedalboard to illustrate the problem. However, I find I cannot, and get an error message
"Could not share a pedalboard: Authentication failure". This problem is probably related to my other problem of not being able to install or update plugins described in: https://forum.moddevices.com/t/could-not-install-plugin-unauthorized/605/8 I've been communicating with acunha offline about that problem and will send him a screen shot of the error.
