Slice discovery problem p_72411 misses files

Hi,

Thanks for this great tool!

I'm loading slice discovery problems, however, the problem p_72411 misses files.
Can you fix this SD problem?

```
FileNotFoundError: [Errno 2] No such file or directory: '/home/user/.dcbench/slice_discovery/problem/artifacts/p_72411/test_predictions.mk/meta.yaml'
