Hi Zuzana,
as fas as I can still remember, there was literally nothin different from all my other projects that I did before.
Space is an issue at times, but I don’t recall it being the case at the time of saving, otherwise I would probably have made the connection. And usually RC gives either a fair warning, does nothing or just crashes.
Your question gave me another idea for a test:
I “saved as” from both files, the old one with the weird behaviour and the new one.
The result is striking: The new project (that I created from the old one with “save as” and then fixed today) created a new file with correct file paths. The old one however created a new project with a file path that is completely unrelated to this part of the project, although in the same parent-folder. How RC got exactly this project (and folder-) name is completely unclear to me. There were a few projects in between and I also used “save as” several times in between. In theory, the error can only be located in entities0.dat or metadata0.dat, since those are the only other two files in the folder and I did not copy those to the new folder when I fixed the problem earlier…
