I found a very small issue that’s never been reported before to my knowledge. Low priority. Not sure if it’s new to 3.0.
When you go to the hero tab and level up a hero class, then tab over to “My Collection” the soul count it shows on that screen does not reflect the souls you used to level up the hero class until you back out to the main screen.
Example: I have 3,200 souls. I level up two hero classes from 1 to 10, using all 3200. When I tab over to “My collection” it will still show that I have 3,200 souls. You have to fully back out of the hero section and re-enter before it will be corrected.
