Building automatically usually requires triggering the "Build" remote with the specific Item ID.

local BuildRemote = ReplicatedStorage:WaitForChild("BuildItem")
local function buildFlatRide(rideName, position)
    local args = 
        ItemName = rideName,
        Position = position,
        Rotation = 0
BuildRemote:FireServer(args)
end
-- main.lua
local config = require("config")
local events = require("events")
local systems = require("systems")
local STATE_VERSION = "1.2.0"
local function safeInit()
  local ok, err = pcall(function()
    -- migrate saved state, re-resolve references
    -- register event handlers via events.registerSafe(...)
    systems.init(config)
  end)
  if not ok then
    print("[MyScript] init failed:", err)
    -- disable noncritical systems, expose diagnostics
  end
end
safeInit()

So when someone posts an “updated” script, they likely changed remote event names or added new bypasses for the latest patch.
