I have checked to see if there any scripts causing this kick, and there are no scripts that use :Kick(). Is this a roblox issue? Is it really something to do with my data loading? How do I prevent this from happening every single time? Thanks.
Do Ctrl+Shift+F (if on Windows) and search “Kick”. It might be that you have a backdoor in your game that is trying to disguise itself. Also check any plugins you may use.
