What you were expecting to happen, and what actually happened?
On Samsung Galaxy Note 5, latest patch:July 2016 Android version 6.0.1
Level up from 3 to 4th level
I just finished Ascension for my Snow Sprite
I selected Level up
Selected 25 soul button
It started to level up and then I got this error code
Error saving user: 2 the service is currently unavailable, KrVC5cpnj42c

There was a problem training your troop. Don’t worry,no Souls were taken and used unless a level was gained.
Checked Snow Sprite - she’s been leveled up.
What are the steps to make it happen again?
The only thing I can think of was I had done two Ascensions with her one moving her from Rare to Ultra Rare and the second one the first Ultra Rare count (1/25)
Do you have any screenshots or video you want to share with us so we can see the problem? Attach them to your post!
