Tested on MacOS version, Chitubox V1.9.5
Steps:
1)sudo mkdir fail
2)Run chitubox as non-root
3)Try to save project to fail directory
Expected:
-No project written, and an error message, as the file could not be saved
Actual:
-Project not written, but Chitubox lies that it saved the file, and all progress is lost (unless you accidentally notice that, and save elsewhere)
