> Good day fellow Developers! I recently installed open edx tutor on a fresh instance. I followed the instructions on the open edx tutor documentation and everything seems to be working fine. But there seems to be a problem with the tutor-MFE plugin. There are times that it works, and there are times that it don’t.

I simply created a new environment variable: `BASE_DOMAIN=charite.local` and a plugin to patch settings.

```auto
from tutor import hooks

hooks.Filters.ENV_PATCHES.add_items(
    [    
        (
            "lms-env",
            """
"SESSION_COOKIE_DOMAIN": ".{{ BASE_DOMAIN }}"
"""

        (

"SESSION_COOKIE_DOMAIN": ".{{ BASE_DOMAIN }}"
"""
        ),
        (
            "openedx-cms-production-settings",
            """
SESSION_COOKIE_DOMAIN: ".{{ BASE_DOMAIN }}"
"""
        ),
        (
            "openedx-lms-production-settings",
            """
SESSION_COOKIE_DOMAIN: ".{{ BASE_DOMAIN }}"
"""
        )
    ]
)

```

Patches append a new variable to the files, it doesn’t replace the old values which creates a duplicate. This seems unintuitive but the last key is always read so it works.
