Since friday I have been unable to train my model with any custom actions. Might this be caused by some changes to rasa_core master since friday? I tried to download and train the rasa-demo and the same problem occurs.
When I run rasa_core.train the terminal prints hundreds of lines saying
rasa_core.domain - Failed to use action action name here in history.
This is the final error:
Exception: Can not access action ‘custom_act_incident_type’, as that name is not a registered action for this domain. Available actions are:
…list of actions in domain
actions.ActionIncidentType
This message is somewhat useless since the custom action named custom_act_incident_type is not in the domain file, but in the actions.py
class ActionIncidentType(Action):
def name(self):
return 'custom_act_incident_type'
I’ve opend an issue for this, including a bare bones example

**Rasa Core version**: 0.11.0a1, commit 89b4651f4a
**Python version**:
Pyth… on 3.6.6 |Anaconda, Inc.
**Operating system** (windows, osx, ...): macOS 10.13.6
**Issue**:
When running rasa_core.train my custom action is not found.
I first receive a warning:
`rasa_core.domain - Failed to use action 'custom_action_hello' in history. Please make sure all actions are listed in the domains action list. If you recently removed an action, don't worry about this
warning. It should stop appearing after a while. `
Then I receive an error:
```

return self.action_names.index(action_name)
ValueError: 'custom_action_hello' is not in list
During handling of the above exception, another exception occurred:
