Hi Anders,
Thank you for reply, sorry for my delay: busied in Conservatory. I am not sure to remember all step-by-step passages, so I will try to be exact much as possible.
I have a Workspace full enough of folders and patches. I was working on a patch denominated “armonici”, with another patch denominated “armonici old”. I have erased the “armonici old” patch, because no more necessary, and then renominated “armonici” to “22 armonici”, inside its folder inside the workspace, but in reopening the renominated patch all objects have desappeared, it was an empty space. That is what I remember.
The same has happened perhaps some other two times with renominated patches.
No problems if there is not solution or explanation, I have recovered all work, importing a patch I had sent by mail, and rebuilding another one by memory.
I have tried to experiment the same procedure with another not important patch, but in this case the patch content has been preserved.
Best
Fabio
