fable contains the function generate.ARIMA() so whenever fable is loaded it prefers to use fable::generate.ARIMA() for gratis::arima_model() instead of gratis::generate.Arima() causing the error like below. Perhaps the order of the classes should be swapped for arima_model() to c("forecast_ARIMA", "Arima", "ARIMA") so this won't be an issue?
