Research direction
Reproduce the failure with the supplied tidymodels example, then trace check_predictions() for the _multinom and multinom objects returned by multinom_reg() and extract_fit_engine(). Confirm the expected simulation path for these model classes and verify that check_predictions() completes without the reported error.
