Steps to recreate:

1. Launch zeditor.exe
2. File->New
3. File->Export->Package

Unhandled exception at 0x00007FFCE271CF19 in zeditor.exe: Microsoft C++ exception: std::filesystem::filesystem_error at memory location 0x0000009B212FB740.

I have fixed this by adding this block before the call to package_create in onExport_Package() in zq_misc.cpp:

Code:

---

        if (strlen(filepath) == 0){
                InfoDialog("Can't export untitled quest", "Please save the quest before exporting").show();
                return D_O_K;
        }

Please review.
