I used a local script to clone a model from ReplicatedFirst in the workspace. The model appeared, but the scripts weren't working that was inside the model. Model had server scripts in it.
local model = game.ReplicatedFirst.Model:Clone() model.Parent = game.Workspace
Cloning from a local script will only clone that item for that player (client). The server won't be able to see it. I think using remote events to trigger a server script to clone that item too will solve the problem? :)
