What you were expecting to happen, and what actually happened:
Some background images disappeared after the recent update. They become a whole color block.
How often does this happen? When did it begin happening?
It has been a consistent issue after the recent update.
Steps to make it happen again
It happens all the time. Downloading all the assets or reinstalling the game does not fix the issue.
I actually didn’t close the game before it happened to me. I just restarted now to try and got the asset download thingy but it didn’t change anything. Just saying it’s probably not directly related.
