Summarize your bug When you browse Galactic Challenge feats rewards, if any of your heroes needs the gear reward and your click it to open the hero screen, the "Rewards" dialog will stay on the screen and it cannot be closed, so you have to restart the game. I checked it several times and it happened every time I did that.
Steps: How can we find the bug ourselves? 1. Open Galactic Challenge. 2. Go to feats. 3. Find any feat reward (I checked only with gear, maybe other stuff will cause the same bug), that any of your heroes will need. 4. Open Rewards dialog. 5. Click on the gear and select any character that will be on the bottom of the screen. 6. Voila, the Rewards dialog will stay with you and you have to restart your game 😉
