[Azhrei]

Describe the bug
Problems running tests against some of the data.

To Reproduce
Steps to reproduce the behavior:

1. Setup a PCGen build (!)
2. Run ./gradlew slowtest
3. See error messages scroll past on the screen

Expected behavior
No errors from data tests.

Desktop (please complete the following information):

• OS: macOS
• Version Sonoma, 14.4.1
• Recreate the environment I'm using via Azhrei/pcgen:sm-fix2 (my GitHub branch with my working set of fixes)

Additional context
I've attached the HTML files generated as part of the build report in ZIP format to make GH happy (~350KB). Unpacking it and opening the index.html in a browser should allow navigation of the different categories of error messages.
