The mod is supposed to remove passageway walls completely. In today's testing the anomaly in the first location when you reach the end of the world map was reachable but the sub got stuck on a wall after loading the next level. I do not know what the devs changed since I made the mod, nor do I know how to get it working again.

Before I forget to mention it too, submarines tend to spawn inside of the walls in the passageways. Only way to get them out was to enable cheats and teleport the submarine.

A game update broke it

Submarines can't enter the passageway going into the wormhole still if they're too big
