Hi Kosmas,
no problem at all. I took the time to fork your repo and apply changes that made it work for me. Please clone the repo GitHub - NikolaMr/rasa-bugs-demo: Trying to demonstrate some bugs in the [Rasa Framework](https://github.com/RasaHQ/rasa), change the branch to no-memorized-action-fix and give it a try.
Btw, how were you debugging things? I’ve used rasa interactive --debug command for that. It is really useful when debugging model issues.
Regards, Nikola
