If player1 creates 5 personal gates, they will connect with each other (networked).
If admin2 creates a gate on player1's network, it will have an empty destination list.

This should not be the case as, fundamentally, the network's name should internally be treated as player1's UUID.

Related to this issue:

Users with access to Central, but who lack access to custom networks, can't make gates on their personal network.
This is because the system defaults them to central; if a username is specified, the system thinks it is a custom network.

This is especially important for the builder preset --
this bug prevents users in that group from being able to use personal networks.
