What you were expecting to happen, and what actually happened?
I expected the troop screen to change to list the troops by life high to low, but nothing seemed to change.
What are the steps to make it happen again?
Go to Troop Screen - Choose Life as Sort option
Do you have any screenshots or video you want to share with us so we can see the problem? Attach them to your post!
Not at the moment, I can get one tonight.
