1 circuit type limit and 1 engine limit

[Saturnorsomthing]

Only 1 circuit type can be present of each type, if you try giving a generalized subsystem core a anti grav circuit and a coralic block a anti grav circuit aswell it will not work as the generalized subsystem core aredy has 1.

Also you can only have 1 engine.
And you cannot have 1 mark 1 engine and 1 mark 2 engine.
Only 1 engine can exsist in the interior

Mostly to avoid bugs ig idk lmao
