Is killing floor 2 still not saving your exp or money?

It's a big issue right now you will need to contact the greatest of the game with your details and issue and they will try and solve it

you have free space in your console?

that's an issue with the game and I believe the company is aware of the issue as several people have complained about this

You will need to contact
Tripwire Support for assistance with that.

Hi ColumnedJet9,

Thanks for reaching out! I'm sorry to hear about the issue with downloading games. Whether you buy a game on disc or download it from the Microsoft Store, you need to install it on your console’s hard drive before you can play it.

• What device are you using?
  
• Do you receive an error message?
  

I would recommend to check out the following troubleshooting resources:

• How to install games on Xbox One
  
• Troubleshoot game or app installation problems on Xbox One
  
• 
  

If so far it hasn't worked you can always try the following If on an Xbox One:

(if it hasn't already been done) a reset of the console since
the problem might be on the actual OS of the console so we would suggest a
Soft Factory Reset(while keeping games and apps)
Before resetting your console make sure of the following:

• There is a stable network connection.
  
• The information for all profiles is known (email and passwords)
  
  
  

Once the setup is complete it will ask if we want to keep settings or manual setup let's do
manual setup.Give it a shot and let us know of any changes!
