Data Center Visiting Broken?

Hello,

I mostly play on Crystal/Diabolos.
I have characters all over, including Aether/Adamantoise

I clearly see the home icon on Crystal Diabolos when logged in and looking at https://na.finalfantasyxiv.com/lodestone/worldstatus/.

However, when I try to visit Aether, it tells me "Your Home World cannot be selected as a destination." despite the destination being Aether, and that is not my home world.

Is this just a stupid/bad way of saying "Diabolos is Congested with a capital C, so you cannot leave it?" Diabolos is a Congested World, but its not my destination.

This appears buggy, since I am just trying to visit Aether from Crystal, but it keeps telling me "Your Home World cannot be selected as a destination", despite it not being my home world (but I do have a character there?).

You don't just "visit Aether". You need to select a specific world on Aether.

After that, you need to make sure you can select a world on Aether. It might not let you, for example, if all the Aether worlds are currently congested.

Are you sure you're not accidentally trying to move one of your alts?

You don't select the Data Center option on the title screen, you have to Right-Click on the character's name on the Character Select screen and pick "Visit Another Data Center"
