Crash Report (if applicable)

No response

Steps to Reproduce

1. Create a new world, and light a TF portal.
2. Enter the portal, this must be done before the world is closed for the first time (the bug fixes itself after first reload)

What You Expected

The portal should function per normal

What Happened Instead

When the world is first created, the twilight forest dimension does not exist. Therefore, the portal will not allow you to enter (though you can still light it), and /execute commands cannot detect the twilight forest dimension.
