Patform : Microsoft Store via PC Game Pass.
As you can see on the Screenshot the loading screen for sandbox mode are completely broken apparently due to missing translation string but it does this even if I change the game language.

Other problem with sandbox mode : I read everywhere that you need to gain one star on a campus to unlock it on sandbox mode... But strangely I've everything unlocked on sandbox since the first launch ( so all campus, all courses, items... ) because of firts glitch i can't return to the menu to create a new sandbox Campus so no screenshot, sorry.

i have seen this on xbox, cant see the coures, just robot heads

Hi Fanriya, 

Sorry you have had this issue with Sandbox Mode.

We are aware of this issue and are trying to resolve it as fast as possible. The glitch with the UI should go away if you select any of the other save slots. Until we have patched a fix, if you set up a second save, you can press it each time the bug occurs when you come back to Sandbox mode. With the UI back to normal you can progress with your original save. 

I have also confirmed internally that having all of the maps available once Sandbox mode is unlocked is as intended.

Thanks for your patience,

Chizel

Ok thank you for your answer.

@Fanriya Hi I', having the same problem. I've tried to start a new save but it isn't resolving the issue :'( I hope the bug fix comes out soon! 

Hi plumbobgob,

Sorry to hear this!

Are you using Keyboard and Mouse to play? Some players have found that plugging in a controller can restore the menu.

We hope to have this fixed as soon as possible.

Thanks, 

Chizel
