Hi,

It seems like it's not working for me either. I placed the source teleporter on Fulgora and another one on Auilo. I loaded the one on Fulgora and set it to "teleport when full," but nothing seems to happen.
Here’s a screenshot for reference: https://ibb.co/H2fyVXk.

Did I miss something?

I didn’t get any error, so it’s hard to provide more information sorry 😅.

The Aquilo button isn't active, so it doesn't see the Aquilo teleporter as a valid destination.

Is the Aquilo teleporter also legendary quality? By default, teleporters that are not the same quality won't link.
The "Link ID" must also match, although it will match if they are both blank, so that part should be fine.
