I am running GPlates 2.3.0 on an Intel Mac (2019 16" MacBook Pro) Running Mac OS 12.6
Sometimes when I try to name and save a new feature collection GPlates imediatly freezes and gives me the beach ball of death. I have no recourse other than to force quit the program. Even worse is that after having done so when I try to re-open the file I’m working on (which I have saved multiple times previously) after the crash, the file is empty and GPlates opens my saved file as a completly blank and new file with my saved work nowhere to be found. So, first the program crashes then it deletes my saved work. What do I do?

Hi Jenny,
So, if I understand correctly, it’s deleting the contents of a file that is **not** the new feature collection you are naming and saving? Or are you overwriting an existing file (eg, using `Save As`), that contains your previously saved work, with your new feature collection (eg, perhaps it’s basically the same content with just some minor changes)? I could imagine a crash (during the file write) corrupting the contents in the latter case, but not so much in the former case.
I’ve just tried saving a new feature collection after digitizing a new feature using macOS GPlates 2.3, and also tried overwriting an existing file (using `Save As`), and it was fine. So to reproduce the problem, could you post some more steps?
It definitely sounds like a bug, and it sounds like it doesn’t always crash, so it might be tricky to reproduce. In which case, if you can PM me a simple test GPlates project (with its data files), or even just the data files, and then detail the steps necessary to reproduce the crash then that’d be great. If I can reproduce the crash then I can fix it and send you new test GPlates build.
