CorePackages - MessageBus

marecikov5 · March 9, 2025, 3:03pm

Hi,

I recently joined our game called Czech Homeless Simulator (which is now currently under review) and I saw error below, I don’t know if this is the reason why is game under review of if this happend when game have been moved to under review status.

Full error (local-side):

CorePackages.Workspace.Packages._Workspace.MessageBus.MessageBus.MessageBus:243: unsubscribing from a message id not subscribed to: PermissionsProtocol.HasPermissions.Response	
Script 'CorePackages.Workspace.Packages._Workspace.MessageBus.MessageBus.MessageBus', Line 243 - function unsubscribeWithMsgId
Script 'CorePackages.Workspace.Packages._Workspace.MessageBus.MessageBus.MessageBus', Line 200 - function unsubscribeToProtocolMethodResponse
Script 'CorePackages.Workspace.Packages._Workspace.PermissionsProtocol.PermissionsProtocol.PermissionsProtocol', Line 166

Expected behavior

I’m not sure what happend, I just joined game. Maybe the issue is, that the game is for now under review, however maybe this is the reason why our game have been moved to this status under review.

I mentioning that in this bug report, because we are not sure what happend. In private message I’m adding my Roblox version and system information.

A private message is associated with this bug report

Core Scripts/Packages cannot be deleted by developers? If you could, you would see games which prevent the Escape menu from being opened. This looks like a bug with Roblox’s code.

Also sometimes getting this randomly upon joining a game.

Don’t tell this guy this is already possible…

Judgy_Oreo · March 9, 2025, 4:07pm

I know that there are ways to do so, but you don’t get there by deleting files stored on Player’s machines

TheRealANDRO · March 9, 2025, 4:17pm

Don’t tell this guy what one of these methods do…

This isn’t even possible, what is bro talking about. I’m going to guess this reply was generated by chatgpt.

Bro it’s not possible what are you even saying

Not ChatGPT actually, but from what i’ve seen games have had the chatfilter deleted from their game which is a core package

Core Packages/Core Scripts cannot be overridden or directly controlled by the Developer. The reason the Chat filter can be tampered with and disabled when not using TextChatService, is that the Legacy Chat is part of the Player Scripts, which can intentionally be modified and “forked”. These are usually for benign systems, such as controlling the Camera or Character.

Ooh spooky hacker with a vulnerability to delete CoreScripts/CoreModules! Instances inside CorePackages can only be modified if you somehow had a vulnerability to elevate your identity and gain RobloxScript capabilities. And if you did have one, deleting modules inside CorePackages will be the least of your goals, you would also have the ability to run malware in the machine of any player that joins your game.

yeah pretty much, easy to do with MessageBusService after I get level 6

Hey everyone - just checking back here, is this something we need to look into?

xyrafrost · March 29, 2025, 6:26am

Seems to still be an issue

Lucatacos2213 · March 29, 2025, 12:16pm
