This video exhibits an issue where I cannot close the chest reward dialog.
I believe the following steps may reproduce the issue:
1. Fight in the arena, and gain a chest.
2. Try to open the chest, and hit escape before it can do anything.
3. Wait for a little while.
4. Open the clan window.
Now the issue should be apparent.
Workaround: Exit and relaunch the game.
Can I suggest a bug category named "UI" or "Interface"?
