Data were 'prettified'. Consider using `terms="c12hour [all]"` to get
  smooth plots.
Can't compute marginal effects, `effects::Effect()` returned an error.

Reason: NA/NaN/Inf in 'y'
You may try `ggpredict()` or `ggemmeans()`.

Data points may overlap. Use the `jitter` argument to add some amount of
  random variation to the location of data points and avoid overplotting.

The variance-covariance matrix is not positive definite. Returning the
  nearest positive definite matrix now.
  This ensures that eigenvalues are all positive real numbers, and
  thereby, for instance, it is possible to calculate standard errors for
  all relevant parameters.

Can't compute marginal effects, `effects::Effect()` returned an error.

Reason: Invalid operation on a survival time
You may try `ggpredict()` or `ggemmeans()`.
