how to get AI/movement in space game to work properly

hey ! im having a LOT of struggles trying to get this working, and neither Gemini3 pro ai nor the UE ai can help me with it as ive been over it dozens of times

ive looked for resources and i cant find any because im strictly working WITHOUT navmesh (its useless without floors and for huge spaces)

so what i have is an AI controller, a blackboard, a data table, and a couple of tasks

now im trying to keep it REALLY simple so i have two tasks right now, one finds the center of a location (and this one works ive tested the output and the vector is correct)

the second one is completely broke and i cant find any way to test it out, even with using both the ai-assistants

so i want to ORBIT around a fixed point (this is a drone flying around a battleship)

and all i get is the drones move sideways to the center of the battleship, and the debug sphere i make just shows up somewhere else and doesnt move

i did what both AI said (they more or less match up) and its with sin/cos

but i have no way to debug it or test or anything and im really stuck
i need to get this done where i can start working on main gameplay

does anyone know how to help, are there specific videos for this, and mostly see its without navmesh thats my main trouble for finding assistance because its a niche thing
