When the offline user Central is not opped (i.e. lacks permissions to use the default network), the edge case handling works as expected.

i.e. they become a uuid if they try a personal gate.

When opped (i.e. has permissions to use the default network), the edge case handling fails.
When they create a {central} or central portal, it will always result in (central)
