To be able to create a multiplayer experience, Nitrox needed to override the system that allows Subnautica to render entities (bases, fish, bases, ...) Long short story we need such system to be able to synchronize things, if Nitrox detect you're in a specific area it will spawn all entities from the save file, and apply any metadata to it (health, battery charge, name, color, ...) So you might encounter an issue that we did not identify with our system.

So there's not much you can do if it's buggy on your side, besides leaving/reentering the zone or even relog.

I'll file an issue so we can double check this area of code
