We had a similair situation like a week ago which involved layered clothing, but that is now fixed.
Personally I have never even seen this type of error message so I’d like some info on what is this and how to potentially avoid it (server crashing).
Game have free models? Because if game have free models, they can have virus/backdoor (serverside). If game not have viruses/backdoor scripts, then maybe in game settings enabled api or http req. Also better check all scripts for backdoor and scripts.
If that not helped then try add anti-cheat to game.
Then exploiter can use kick script, or thing named DarkDex.
And that “Player has been removed from the DataModel” mean that player was kicked from game (i know this from pinewood computer core admin cmds kick with that way).
Then i think exploiter use executor and execute scrip what can kick or crash server.
(I recommend using free models that have a lot of likes) btw if that SS then try look close when you join game because i know that many backdoors executors can be visible for 1-3 seconds while game loading.
I might’ve fixed it but unconfirmed yet, if in a couple hours nothing happens means it worked.
And since its just disabling a backdoor so I’ll give the solution to @The_0Boomy0 if the backdoor’s gone.
