While testing I save my RRO in the browser, because we do not have a UNDO button. I increased the number like this:
ransom 1
ransom 2
ransom 3 etc.
Then for a while I saved it as ransom 4, a few times, because everything went well.
But when I saved ransom 4 in the browser, as an empty RRO by accident, I could not go back to ransom 3 or ransom 2, etc. They do not show in the "Load" from browser data.
I lost the RRO completely.
It seems that the last RRO is overwritten every time.
Diff:
I was able to replicate this. It looks like it's a problem with the new diagram name being the same as an existing diagram's name.
This has been fixed. The test site has been updated with the changes.
