Most of the time, players will be sent to a different game, then sent back to my game. I do not get teleported but I do get an error saying it couldnt teleport me. The game won’t tell me what script its trying to teleport from. The only error says “raiseTeleportInitFailedEvent: Teleport failed because This game has not been approved, yet. (Unauthorized)”.
Check your plugins and all scripts for require, getfenv, and other loading strings. You have a backdoor in your game. This happened because you used an infected free model or a malicious plugin. The people that made the loading scam (builderman and snape as they go by) are also the owners of doggo admin and both of those are loaded together, meaning someone who has purchased doggo admin has access to the server side.
And regarding your previous attempt, you are not going to find a backdoor by searching for teleport or marketplaceservice. All of these backdoors use loaders which you can look for using the methods I put above.
