Hydros making parts not show up

Im having issues with Hydros. When I add a hydros section to my jbeam, that part doesnt show up, and generates no errors.

Without hydros in code:


with hydros in code:


As you can see, simply commenting out the hydros section fixes everything. Im not sure whats wrong.

So I fixed the quotes but now it crashes the game when loading the vehicle.

 

Weird enough, taking the default slot type out makes everything work. but putting the name there makes the vehicle crash the game. Also weird leaving it blank still loads that part.
