Yes man… the airship is at the workplace while the NPC is been spawned from ReplicatedStorage.
I figured that it was the issue, not sure how address though…
So the NPC and the airship are in workspace? It should work fine then if you just run the scripts like before.
At the end both lives in the workspace, but the Airship is originally in the workspace (therefore it doesn’t float on server) while the NPC is originally on the ReplicatedStorage and gets cloned into the workspace.
