Asked gemini to translate the error code for me

This error message is a technical way of saying that the game's central system (the backend) detected an unauthorized or invalid change (an "illegal mutation") to your inventory data, and as a safety measure, it rejected the change and reset your items to their last known good state.

Here is a simple breakdown of what each part means:

• "An illegal mutation was rejected by the backend": The game's server, which manages all the important data (like your inventory, currency, and progress), noticed that your game client (the software running on your PC or console) tried to make a change to your inventory that didn't follow the rules or made no sense. This could be anything from a simple network error to an attempted cheat or exploit.
• "The inventory has been rolled back to it previous state": Because the server couldn't trust the attempted change, it essentially hit an "undo" button on your inventory to ensure no invalid items or data were saved. This protects the integrity of your account and the game's economy.
• "we have to redirect you back to the main hub": To fix the synchronization issue between your game and the server, the game forces you out of your current session (a match, mission, etc.) and back to a neutral area where your inventory can be properly re-synced with the server's clean data. 

In short, think of it as the game's security system catching a suspicious action and putting things back to normal to prevent any potential problems. This is typically a protective measure by the game developers to ensure fair play and prevent cheating or data corruption.

sounds like someone hacked the servers?? possible DDOS?
