What you were expecting to happen, and what actually happened:
I actually expected the current update to address this issue. As I had been experiencing something similar at a smaller scale. The smaller issue began two updates ago. I first noticed it in Delves, when there was a Naga team. The card art would show as this blurry brown image. It also occurred with some spell art, and enemy card art during a Bounty event. It also would occur during the loading screen between battles with different troops. This was a small aggravation that I thought would sort itself out with subsequent updates. This did not happen. Now with the latest update. I am experiencing this issue more globally.
How often does this happen? When did it begin happening?
The current issue became worse today (current screenshot). I had updated yesterday without issue. Today when I logged into the game. There were additional assets to download. That were not there yesterday. I always go to download all assets after an update. Today after additional assets download completed. I was left with the current mess.
Steps to make it happen again
Apply update. Download additional assets. Play the game.
