Liberator Achievement Not Popping Xbox

@NoisePilot Hey, so for achievements, EA has no actual control or the ability to "fix" them if they are on the console. Xonsole achievements are designed to pop on your console account for each game regardless of the game. When these get reported to the developer fo the game you are playing, they can test it, and see if they can get it to pop but ultimately these would then be reported to the console the player is on to see what is happening.

Typically, it's a matter of stuck data or a corrupted save. Below are steps you can take to see if they work.

 Xbox Series X

• Quit all running Apps (For Series X|S consoles)
• Remove any connected device, or additional USBs from the console then restart the Xbox and check for updates
• Try the steps in our Connection and Advance Connection Guides
• Open you're Xbox NAT Type
• Change DNS settings (You can use the public Google DNS primary: 8.8.8.8, secondary: 8.8.4.4) 

Persistent Storage

• Go to settings > Select Device & Connections > Then Blue-Ray
• Select Persistent Storage > Clear Persistent Storage

Alternate Mac:

• Go to settings > Select General  > Then Network settings
• Go to advanced settings > Alternate Mac address > Select clear
• Select restart

I would also suggest saving your game as a new save file, loading that save file, and trying changing the difficulty and playing to see if it will pop. If it is stuck, that means your saved data isn't syncing like it should.
