Ozone (x64) v3.24g on Ubuntu 20.04.3 LTS (in a VirtualBox VM on Win10-Pro).
If I do 'Save Project as' to a folder where I don't have write rights, the save fails (of course) but Ozone gives no indication of the failure; in fact, the Console suggests that it succeeded:
The first attempt (ringed red) failed;
The second attempt (ringed green) succeeded.
In both cases, there was no error message or warning, and the console output actually suggests that both succeeded.
