The anti-teleport net over the tower, rendered irrelevant the moment teleport restrictions were lifted.
Throughout the siege the net had blocked escape from the Nest Tower, but the instant the system announced that all restrictions on teleportation were lifted, Carl noted that with the deactivation of the teleport ban the net was no longer an issue.
That left him and Princess Donut free to use the escape hatch behind them to Area 52 whenever they chose, which mattered only after the Astral Paw massacre was finished.
The escape-blocking net neutralized by the lifting of the teleport ban.
